RE: how to make tomcat faster

[Jackson, Stephen]

One item I found to increase tomcat performance is to run tomcat with the
-server option

HOST your production using a UNIX box.  I recommend Solaris x86.
However, a good tightly configured linux machine would suffice too.
If you can swing it, get dual cpu's and max memory.

Curious to know what advantage Solaris x86 offers versus Linux.
Is it thread handling?

well to install jasper from the 4.1.7 you only need to take 2 or 3 jar
files and replace the old ones in tc 4.0.4.

the jar files are from 
tc.4.1.7 : 

common/lib/jasper-compiler.jar
common/lib/jasper-runtime.jar
common/lib/commons-collections.jar

and if I remember it correctly I also moved the : 
common/lib/ant.jar 

to my tc.4.0.3 installation.


I am sorry but I will not explain connection pooling here, as it's been
done serveral times and you can search the mail-archive for information
on that matter, I use a pool from www.bitmechanic.com, but there are
several others available. Even sometimes a pool is distributed with the
JDBC driver, I'm not sure about the free one from microsoft, but it
might have some pooling implemented.
Caching is something you need to implement into your jsp-pages, it's
usually done by using cache-tags that implement "fine-grain-cacheing",
this will make you able to decide for how long each segment of your
response is cached. I've been using OSCache, from www.opensymphony.org,
there is also a cache-taglib in the jakarta domain. 

My guess is if you do this, your application will get 5 times faster
than it is right now maybe even alot more depending on how you do
it.
About the System.out.println, you should just implement Log4j logging,
it's powerfull, and easy to use. 

There are many things you could look at, for example, if you are using
HashMaps alot, you might find it alot faster to use FastHashMap, or if
you are using Vectors alot you might find it faster to use/iterate
through LinkedLists, if you are using out.write alot, you might want to
make use of StringBuffer, append to it while rendering the jsp, and only
writing that to the response (one out.write instead of many.. it should
be a little bit faster). 

For benchmark-testing I've used both jmeter and "Microsofts
Web-Application Stress Tool", and here I recomend the MS tool, it's very
powerfull, and gives you good reports.

RE: how to make tomcat faster

[Anoop Kumar V]

hi Reynir,

That is a lot of information u hv given..Thanx for that. 
But my problem is that i cannot change the code at this stage as it is
already in production.
So can you tell me if some of these things are possible by just editing some
of the configuration files
like server.xml etc. The jasper part i think i can do, coz i hv d/l the jar
files.
I did that, restarted tomcat and my application, but it just bombed, i get
exceptions on the TC console
BuildException, and later after placing ant.jar in another place (there are
2 libs, common and server)
it gives me JSPException, .. of course i am testing this out on my local
m/c.

tell me if there are any other ways pls.

RE: how to make tomcat faster

[Anoop Kumar V]

hi,

OK..maybe i shd hv included that in my first message..anyway its here.

This application has considerable database work with a few reports thrown in
here
and there. I have just one servlet, remaining are all jsp's (about 50 jsp's)
and about 25 beans and other class files(MVC). I use MS-SQL Server as the
database.
no connection pooling.. as i felt the number of users are too small(100 -
250 
at peak time) and yes, every request fetches info from the database. So i
guess
i need to know how to enable connection pooling.
Also the cache part.. there are some entries in server.xml which seem to say
"save session on restart", but i was not sure so i hv left them alone. So
tell me how
can i enable cache too. 
There is hardly any static content in my application, and what i meant was a
relative
slow down compared to when Tomcat was stand-alone (or with Apache). Yes,
even i am using
AJP1.3 connector with isapi_redirector.dll filter. 
About System.out.println...yes i had quite a bit until now.. which i hv
removed.. but
i do not see much of a performance improvement (need to check at peak time,
again).
  Need some more pointers regarding jasper, does it coem along with tomcat,
and how
to set it up. (is it similar to Jikes?)

Hi,

please inform us of what kind of work you are doing with tomcat, are you
requesting informations from databases for every request, are you using
connection pooling, are you using cache, are using jsp alot ? 
There may be many places you can optimize performance in your application
just as well as increase tomcat performance. 
One thing I did to increase performance with t.c.4.0.4 was to use the Jasper
from 4.1.7. Because the threshhold of my application is in jsp-rendering
time, and the tags my jsp pages use, this increased performance about almost
100%. 
Using IIS, if it's correctly configured should help alot, as it will deliver
all static documents, such as jpegs, gifs, html etc, and take the load of
delivering this away from tomcat, so tomcat will only need to handle the
jsps and servlets.
If IIS is slowing down the whole thing, IIS is either wrongly installed, or
the connector. I've used AJP connectors along with the isapi_redirect.dll
filter. 
Remember also, system.out.println logging can slow everything down a bit, so
try to do the least of that 

but for starters, you should try using the jasper2 from tc.4.1.7, it really
works well.

Remember also, system.out.println logging can slow everything down a bit, so try to do 
the least of that 

but for starters, you should try using the jasper2 from tc.4.1.7, it really works well.

hi,

i have been developing using Tomcat 4.0.1.. and i hv had no problems about
that.

Now i have moved all my applications on to the production server, where
hopefully i
wdnt be making any more changes. But i want to make Tomcat respond faster to
requests.
Obviously the production environment shd be different from the development
one..so 
can someone detail me on what changes i can make to make Tomcat quicker to
respond.

Thanx in adv,
-anoop

RE: how to make tomcat faster - performance tuning

[Anoop Kumar V]

Ohh.. let me also add..
The number of users accessing the application is close to about 100-180 at
peak time.
And i hv IIS configured with Tomcat (which has already slowed it down..was
faster as
a stand-alone on port 8080, but had no choice). And its running on
Win2K(obviously).
Hoping to get some expert opinions abt this.. thanx...

perform better.
