Tomcat 4.0.3 performance

[William Au <bi...@cnet.com>]

I did some performance benchmarks of Tomcat 4.0.3 against two other appservers.
Tomcat's performance is even worse that what I has expected.  Tomcat was at
least still in the ball park when serving simple JSP pages.  However, database
access (I am using Jakarta Commons collection, pool, and dbcp) does not scale
for medium and heavy load.  JSP taglib performance is plain terrible and
unacceptable.

My results pretty much rule out the use of Tomcat 4.0.3 in the production
environment for us.  Anyone out there using Tomcat in their production
environment?  Any other comments regarding Tomcat's performance?

Tomcat SSL + client Authentication.

[Spiros Vazaloukas <sp...@necis.be>]

Hi all,

I think this question has been posted before but I can't find an answer in
the archives:

When I enable client authentication in the server.xml (clientAuth="true") my
https://localhost:8443
call returns nothing (The page can't be displayed). I've create the CA and
tomcat certificate
and I've imported them to the keystore but no luck......

Any idea?

Thanks
Spiros

Hey Bill.

For those interested, can you send out:

a) what your platform was (OS, JDK rev, etc)
b) what your hardware was
c) The results of your benchmarks

This is useful information for folks as a whole and it would be great for
everyone to have it.

Thanks!

You should be able to plug a different connection pool if you need to.

This is because of a Sun JVM performance bug (don't know if IBM VM would 
perform better). A workaround for it got added in Jasper 2, so I 
recommend trying Tomcat 4.1.3 Beta to see the actual performance.

For more details, see:
