Paging Principals
Hi, I have an app that queries a table and displays a subset of the query results in a paged format, showing only 10 results per page. Some queries will return upwards of 1,000 rows. This query joins quite a few tables - say 8 or so, however the query itself only requires one table to obtain the basis of the dataset(the rest of the tables in the join are used for display info or 'cosmetic' type information). Generally speaking, which of the following would be more efficient: Option 1: - Query database, joining 8 tables, get entire dataset (1000 rows) - CFOUTPUT / Loop limited to start row (page ordinal) and maxrows (10) Option 2: - Query database only based on the results of one table (1000 rows) - Cfoutput / Loop limited to start row (page ordinal) and maxrows (10) - within output loop, perform second query joining the 8 tables, based on a single primary key returned from the initial dataset. (returns single row) In essence, the question revolves around whether it is more expensive to pull an entire 1,000 record joined dataset in one shot, or to make the initial query lean, and then do ten consecutive queries performing the join. The former likely incurs more database load, while the latter would incur more interaction with odbc. Whew. Interested in your answers!

RE: Paging Principals
Hi, Good idea. A cached query wouldn't work for us, unfortunately, as the data changes almost by the minute. Geoff B -Original Message- From: Ben Doom [mailto:[EMAIL PROTECTED] Sent: Wednesday, September 10, 2003 9:43 AM To: CF-Talk Subject: RE: Paging Principals When I had something like this, I used the full query but only retrieved the top n, where n is the highest index to display. So, if you are displaying 10 per page... page 1, n=10 page 2, n=20 and so on. Maybe not a perfect solution, but dropped average processing time a lot, since people would generally either narrow the search or only look at the first page or two.

Win2k Clustering and CF

If CF begins queueing too many requests, or is not responsive, I need to remove the box from the cluster.

URGENT! - Help With OLEDB
Hi, With some playing around, I have found that OLEDB seems to be much more stable that ODBC. For awhile, we were recieving random disappearances of ODBC datasources, which required a reboot. Anyway, the problem I'm having is that the results from OLEDB aren't consistant with those in ODBC. Example: I have one query that returns a series of results, and the query is dynamically generated. This works *perfectly* under ODBC. Under OLEDB, it returns zero records. I've tried even moving the query to a stored procedure and generating it dynamically from there. No good. Regardless of what I've tried, simply changing from ODBC to an OLEDB datasource effects the results returned. Any ideas, thoughts, help?!?

use isdefined, you'll need to use a real cfif.
What you can do is this:
CFIF isDefined('form.categories')
cfset variables.categories = form.categories
cfelse
cfset variables.categories = ""
/CFIF
IIf(variables.categories is "", DE(''), DE(variables.categories))#
Or:
IIf(variables.categories is "", DE(''), DE('#variables.categories#'))#

RE: Why Netscape's serious lag time?
Hi, Netscape is a little freaky about tables. You have to make sure that all of your width / height calculations are defined, and are accurate. On first glance, I found that you have a table with a width of 600 contained within a table with a width of 585. Netscape is probably trying to recalc all the tables, which causes the lag. I didn't dig any deeper than that though...

Hey all, Might anyone be able to offer a plausible solution to Netscape's lag time at the following URL? It appears to be loading the tables and *all* of their images before displaying the page at all. This problem exists in other sites I have worked on and I've yet to find a solution outside of not using tables within tables. I can't imagine it being caused by the CF code, but I can't really see what's causing it to happen. http://www.awgear.com/products/index.cfm?fuseaction=dsp_productsD epartment _name=Sleeping%20BagsDepartment_img=sleepingbag_tn_title.gif or just: http://www.awgear.com and click sleeping bags or most all of the links.

RE: Cold Fusion vs. Java Servers: Performance
Any feedback on JRun performance vs CF? -Original Message- From: Ed Toon [mailto:[EMAIL PROTECTED]] Sent: Tuesday, August 22, 2000 5:15 PM To: [EMAIL PROTECTED] Subject: RE: Cold Fusion vs. Java Servers: Performance Cold Fusion doesn't stand up to them. At all. I've watched a couple of sites move from CF to ATG Dynamo and WebLogic, and the performance just can't be compared... they knock the socks off of CF. That isn't to say that CF can't be used in high traffic sites - if you want to have a few dozen servers running. I personally love CF for intranets and other low traffic applications, betas, etc.. but it's just not in the same league as those guys. As we move closer to JRun/CF integration it will start to compete though. ;) Ed -- Archives: http://www.mail-archive.com/cf-talk@houseoffusion.com/ To Unsubscribe visit http://www.houseoffusion.com/index.cfm?sidebar=listsbody=lists/cf _talk or send a message to [EMAIL PROTECTED] with 'unsubscribe' in the body. -- Archives: http://www.mail-archive.com/cf-talk@houseoffusion.com/ To Unsubscribe visit http://www.houseoffusion.com/index.cfm?sidebar=listsbody=lists/cf_talk or send a message to [EMAIL PROTECTED] with 'unsubscribe' in the body.

CF Performance
Hi, I know this comes up a lot... but, I'm looking to drastically improve the performance of one of our CF servers. We are in the process of fine tuning some of our code so that it follows some of Allaire's suggestions on performance tuning. One server I'm running has Cold Fusion at 43 megs memory usage, and Inetinfo at 48 megs. Is that... normal? Lastly, I'm wondering, what others are running for server hardware for large scale applications?

Verity vs. Freetext
Hi, I have a large scale application that will contain a lot of data, and will require that users do frequent text searches. I am running SQL Server 7. Which would be faster - a verity collection, or using SQL 7's Full-text indexing? We are probably talking about well over 20,000 individual records.

Performance
Hi, I'm looking for some advice on tuning SQL Server. We have a DB that's (let's say) 100 tables, heavily normalized, with over 250,000 records in at least 10 primary tables. For many screens within the application, we need to do two or three queries, and sometimes quite a few more, all of which must utilize the primary tables containing the most data. This obviously drags the server to its knees very quickly. The server we are running is fairly capable (single 500mhz, 512 ram, Win2k), and is dedicated only to SQL / DB tasks. We are considering adding another 500mhz to the server, which may help. In a heavily normalized database, what can one do to improve join and sub query performance? The queries mostly aggregate data for financial purposes, so some of this could be stored in a temporary table populated by a trigger, or something similar. Cached queries will not work in this situation. Help?
