Subject: CF Performance re: multiple CPUs, Cores, Servers, Virtualization

We're looking at throwing more hardware (both upgrades to existing servers as 
well as new or replacement servers) at our mix of applications to improve 
performance.  I'm looking for insights from personal experiences on a couple of 
approaches.

Our application mix that needs the performance runs mostly between midnight and 
mid-morning, and is a suite of CF scripts that interact with webservices from 
the major search engines.  Lots of XML parsing and processing with lots of 
database activity to store the data.  Some of the XML files are large, and 
therefore use up a lot of JVM when being processed (since at some point in time 
there needs to be a copy of both the CFHTTP data returned from the webservice 
as well as the structure being created by the xmlParse function).  We have a 
pretty well configured SQL 2000 server, although the production could admitedly 
use some tuning.

These are Windows servers, so we have the inherrent limitation of ~1.8gb 
address space, which boils down to around ~1.4gb available for the CF apps 
running in the JVM.

What about just running a stack of multiple servers?  This helps solve the 
Java/CF memory space problem.  What about just running a stack of multiple 
(cheap) workstations, possibly with dual-core processors, instead of a big 
honking (expensive) server (we'll call this the Google approach)?

What about virtualization?  Any experiences using either Microsoft's software 
or VMware on a server with an instance of CF on each of them?  That also solves 
the memory problem (presuming sufficient physical memory), but would seem to be 
highly sensitive to the number and effectiveness of the processors/cores.  It 
seems like it might have an administrative advantage over simply running 
multiple instances of CF on the same server since I wouldn't have to worry 
about port numbers and such on the same server, because each would be running 
on port 80 on its own IP address within the virtualized server.

Any other alternatives?  I can definitely find additional work for these 
systems to do during the daytime, but the real crunch is to get all of that XML 
data processed by CF during the nighttime before people show up in the morning.

TIA,
Reed

Hi:
I wanted to introduce CF to some webdeveloping classes (I'm struggling to make 
them start a CF course class) and I need a Video Tutorial CD/DVD which I can 
suggest as a start point for them.
Lynda.com has one but it is for MX and the Dreamweaver 8 Dynamic Development is 
mostly about DW.
VTC.com has one but I couldn't find it in my area.
Is there any other one? From Novice to Advanced or even Basic.
It will be great if the movie uses DW or CFeclipse as the editor.
I know you may suggest ColdFusion MX 7 Web Application Construction Kit (Ben 
Forta) or other cool books but I prefer a Video Tutorial because it will be 
much easier for managers/developers to start.
Thanks
Benign

Hi:
I was searching for job offers in Australia in here http://mycareer.com.au/ 
If you search for CF job offers it brings only 23 jobs which more than half are 
not even only for CF developers and some are for other languages like PHP or 
.NET. When I searched for PHP it came out with a few hundreds but with .NET 
2334 matching results!!! 
I love CF but it seems even Python is more popular or at least the search 
engine comes with better results with it (about 50 offers).
I really don't understand why such a powerful and easy langauge should have 
such a low job offers in Australia! I really don't know about USA but it seems 
the same thing is true in the USA to.
You know I just say it as a theory cause I really love CF and I won't migrate 
it till and only if Adobe kills the product but it seems if we started with PHP 
or .Net at the begining now we were more and better employed than now.
Please write your opinions.

Re: AJAX Libraries

[Ariel Jakobovits]

YUI also has a good Custom Event framework and one very important parameter 
built into all of their event handling functions that you will discover is 
essential.

But just to add, I thought their widgets were poor. Ext has the nicest ones but 
hardest to work with. Dojo's API looks sloppy. MooTools has beautiful examples 
and simple code. And I don't know much about Prototype except that I didn't 
choose it.

This is what I was doing before I decided to move to Flex.

Just like to throw in that unlike the other toolkits, jQuery is a unique and
expressive language to use for adding your own javascript functionality to
webpages with very little coding. It teaches you the DOM structure very well
and will hone your CSS/XPath skills. Discovering it was like writing my
first Lisp program, except that I ended up doing lots of things with my
javascript capabilities.

I think jQuery's strength lies in its ability to target and modify specific
DOM elements. Conversely, I think its weakness is that you give up on a lot
of its power when using other people's plugins. I believe there are lots of
plugins because it is easy for people to create their own functionality, not
so much because the community at large is asking for them. Dojo has
pre-built widgets you are encouraged to use, Ext even more, and a
developer's strength is based in his/her ability to use the existing
widgets. As a jQuery programmer, you want to be good at adding the
functionalities yourself on the fly as you decide to add them.

Also it also good to know that the list of recognizable brands have deployed

Finally, it is also good to find reputable CF gurus (or even novice to

Re: Matching database field names with label names

[Ariel Jakobovits]

don't forget that valid sql names are likely to be valid cf variable names, so 
a structure with labels[table_name][field_name] is likely to work well.

Subject: Matching database field names with label names

I've had a request for an "audit trail" for a SQL Server based 
application. I've gotten triggers set up in the database that logs all 
changes, and records the field name, plus old/new values for 
comparision. This is, as usual, an "add on" request after all other work 
was finished and never in the original spec. Oh, they'll pay, but that's 
not the problem...

The client wishes to be able to view the audit trail for any specific 
record between various dates and various other blah, blah, search criteria.

No problem here.

OK, what's now giving me a fit is that they don't want to see the 
database field name, but the label that's on the original form. So, in 
my "audit table", I've got stuff like:

field_nameactionold_valuenew_value
IV_1_predefUpdatewhatevernew whatever
VIA1_PPAUpdatewhatevernew whatever
II_B_dtON_dUPdatewhatevernew whatever

This stuff span eight tables and several hundred fields

OK, in code, what would you think the most compact/fastest way to match 
up the "field_name" and the label name for display purposes?

All I can think of is to set up a huge array:

 (field name)
 (label name)

. and then loop through it looking through matches in 
audit_table.field_name.

Seeing that you could end up looping through the entire array dozens of 
times just to display one set of results - don't seem too good.

Anybody got any other ideas?

Re: Reducing phantom sessions?

[Ariel Jakobovits]

What about identifying the bot requests and assigning them all the same session?

Subject: Re: Reducing phantom sessions?

Terry,

The only thing you're doing is setting the timeout for a bot to one second. 
They still create a session, but the session is destroyed immediately. The 
whole problem is that sessions are created for each bot hit and exist until 
the session times out. If you have one bot hitting ten pages, that's ten 
sessions. If you have ten bots hitting ten pages, that's one hundred 
sessions. If the session lasts for five minutes, then you can see how it 
will simply ramp up RAM as the bots come in.

House of Fusion gets tens of thousands of bot hits a day, and by using this 
technique, we show no loss of memory or performance.

After a certain field is checked, it uses a  tag and the url, but I

method of clicking the parent menu item in order to see the submenu items 
instead of the rollover functionality as now we have a 3-click navigation 
instead of a 2 click navigation to get to pages within folders.  The url for 
the site is www.jetstreammedia.com then click on the jetstreammedia puzzle

I have a dedicated server - mostly for "personal" use... ie, my own

I currently share the server with 1 other person, and I'm looking for
2-3 other people interested in sharing it.

It's a nice little dedicated Linux box at viviotech, unmetered
bandwidth (with a 3mbps pipe or something).  coldfusion 7.0.2 is
currently running on it.

As part of the "co-op" you'll get to do whatever you want pretty
much... ie, however man web sites you want, plenty of disk space to
share, etc.  root access if you want it but I'll happily manage it.

the cost would be $25/month paid every 6 months.

Please email me off list if you're interested.

Hi Neil,

I am still trying to convince you to try Railo :-) Since CFCompile is 
not an option you can tweak the JVM settings for CFMX. Read more here:

http://java.sun.com/docs/hotspot/VMOptions.html
http://developers.sun.com/techtopics/mobility/midp/articles/garbage/index.html

Since in Railo 1.1 we use a bytecode generator, the compiling time is 
around only 20ms per file... Before it was around 200ms...

What is the "best" way to store client variables? We are in the process of 
completely redesigning our website and considering changing the "clientstorage" 
attribute in cfapplication from a named SQL datasource to "Cookie" to prevent 
having 100,000's of records pile up on our SQL server. 

The primary use of this would really just be to allow the user to have their

Any arguments one way or the other?

Re: Client-side validation or Server-side Validation?

[Ariel Jakobovits]

I think we, as a community of developers, should address the real problem here. 
Actually there are several, but they are all related to the basic need for a 
framework that will make our programming lives easier when dealing with the 
topic of input validation. I mean, look, how many of us were adding as much 
javascript to our sites as we are now before toolkits like jQuery came along?

So, for example, there is this and that validation plugin, and those are 
general steps to provide tools or frameworks to simplify the process of adding 
client-side validation. But why stop there? Because we don't want to tackle the 
larger issue?

See, I understand everyone's perspective on this issue. Some have to care about 
non-javascript users, some don't need to care about any particular user because 
its not their business. Some care, but don't have the time or the resources or 
the patience or the know-how. But I'm sure that if we had a "magic" solution 
that allowed us all to have client-side validation, both client-only and AJAX 
based, as well as non-javascript-degradable sites, as well as complete 
server-side validation because we had lightweight javascript code, plenty of 
server processing bandwidth and memory, and the ease of installing all this 
code into our applications, then we would all do it together. We only bicker 
because we all are balancing our capabilities with our priorities and we are 
each coming up with different conclusions.

Truth is, with client computer processing power where it is, and network 
bandwidth where it is, and models like Amazon web services offering extremely 
cheap and efficient server processing power, there is no reason that we, as 
developers, can't start considering having it all. The way I see it, we should 
probably start assuming that we will have to have it all because that's the 
direction publishing on the Internet is going. I mean, let's say you aren't 
worried about malicious attacks, so you figure client-side validation is 
enough, but then one day you realize that some mashup service is posting 
directly to your servers. That's not bad, just unexpected.

So, how about we start with saying, "We want to be able to validate client-side 
and server-side with none, one or many AJAX calls, minimize complexity of code 
installation, and have no users complaining about sites that don't work without 
javascript" and begin to develop a solution to do that. It's possible. I am 
convinced of that because of what I have seen become possible with jQuery alone.

Just as code generation tools aim to ease the work of becoming object-oriented 
by creating bean classes for us based on database schemas, we can develop a 
framework to take our basic needs, expressed in minimal terms, and translate 
them into whatever demands or expectations we have. We could develop a language 
for expressing validation generally and write tools that produce validation 
code in javascript, php, ColdFusion, ActionScript, etc. for us and not feel 
that we have to choose one or the other. This would be just one element of a 
complete solution. If we are worried about how such code gets incorporated into 
a larger framework, then maybe we need to design a framework that is loosely 
enough coupled, as we all want our frameworks to be, to incorporate these 
things easily.

I know this has been done before, or at least attempted. But maybe its worth 
another shot by us. Let's start by compounding all of our requirements for this 
and see if we can develop a solution however slowly. Might be a good project to 
be based in the commadot website.

I submit my remaining time for questions, comments, and lambasting.

Re: A Question for Development: Ajax Now or Ajax Later?

[Ariel Jakobovits]

HTTP can carry any message that I can imagine, thus it can be the delivery 
mechanism for any language to express an RIA. The only argument that makes 
sense is that the _browser_ is an inefficient mechanism for delivering RIA as 
opposed to Flex.

Regarding Flex, I hate compiling things when building apps. I work 
incrementally and it drives me nuts.

The fact that it's easy to do AJAX development is irrelevant. The fact is
that HTML and HTTP weren't designed to deliver applications, and no matter
how good your libraries are, they can't fix the limitations inherent in HTML
and HTTP. Let me know when you can do client push, or database concurrency
management, or anything else that you can take for granted in a traditional
client-server environment. And I'm not talking about hacks to simulate those
things - I already know those intimately - but the things themselves.

Why shouldn't we be able to have that sort of power with distributed
multiuser applications? There is no reason, other than inertia, why we
can't.

I think you misunderstand what I'm saying. I'm not saying you shouldn't use
AJAX, or HTML, or anything else. I'm not saying that you should immediately
rewrite everything in Flex. What I am saying, is that HTML is a
fundamentally flawed delivery mechanism for applications, and that
ultimately we should be looking for a replacement (perhaps Flex) rather than
an incremental improvement (AJAX).

That said, Flex applications can perform reasonably well even with
relatively slow connections. I should know, since I often use a slow
connection (my cell phone as a modem) for all sorts of things. 1xRTT is a
little faster than dialup, not much.

Re: Session timeout problems

Does the use of AJAX also make race conditions more likely?

If you aren't using frames (or any other techniques that could request
multiple pages in the same session simultaneously), then session scope
race conditions are very unlikely.

Re: SOT: advantages/disadvantages of using CF and XSLT.

[Ariel Jakobovits]

XML/XSLT does not query databases or produce structures that can be forwarded 
to web services and other applications. CF is a good framework/backend tool 
that can serve raw data to be altered by XSL.

Subject: SOT: advantages/disadvantages of using CF and XSLT.

Greetings,

Have a general question about XML/XSLT and CF. One of the powers that be is 
making noises about limiting the use of CF etc., etc., etc. One of the 
arguments he's using is that XML/XSLT can handle most data display. 
Unfortunately I know know enough about XML/XSLT to discuss the issue 
intelligently and show where he's incorrect with this. So in general, what are 
the advantages/disadvantages of using CF in conjunction with XML/XSLT over just 
using XML/XSLT alone?

Any suggestions are appreciated.

thx,
larry
