Tomcat performance issues

[AMRAN121]

Hi All

I have designed some jsp pages which extract from a database. But the pages 
can take upto 5 minutes before they show the content. Is there anyway I can 
pinpoit where the bottle neck is. My current settings are APACHE +  MOD_jk + 
Tomcat 4.03 (could the bottle neck be my Apache and tomcat servers being on 
separate machines?) . Are there any tools that I can use to test the 
performance of my servers?

Regards 
amran

Use a tool like Optimizeit from Borland or wrap your methods in
System.currentTimeMillis().  That will at least help you narrow down your
search.

Good luck,
Subir

if you setup mod_jk in an not optimal way, you get long timeouts until,
the page is shown, but 5 minutes is a bit to long.

Our tests here indicate a mass performance speed up, if we don't chain
apache and
tomcat and use tomcat standalone.

If you disable the database connection, the time is still long?
Are you sure is not a db problem?

Tomcat performance issues with W2k - SP4

[Benito Garcia]

Hello.

I have Tomcat 4.0.4 in a  Windows 2000 SP3  ( and a Oracle DataBase ) working fine 
and with good performance.

When installing the Service Pack 4 in the Windows 2000, all continue working OK, 
but wit a great loss of performance.

If I uninstall the SP4, the performance remains degraded. I need re-install 
Windows 2000 - SP3  in order to get good performance again.

I'm a little bit confused...

Tanks in advance.

Benito.

Tomcat isn't the only application.  IIS suffers as well.  Are you using
Server or Advanced Server?  There are some major problems with Advanced
Server after installing the patch.  I think you should ask MS about
this.  Also check with your VM manufacturer.  We have some ISAPI
applications that run in IIS that have suffered as well.  We are working
with MS currently to try and figure this out.
