Hi Andoni,
i have a proliant server and when i installed tomcat at first time this
runs slow, taking few seconds to complete one request. Change config of Tomcat
and JVM. Use programs like Jmeter to measure your system performance.
This link help you to improve JVM performance.

About tomcat, change the connector properties in server.xml:
<Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
port="8080"
minProcessors="50" <---- adjust min and max processors
maxProcessors="500" <----
enableLookups="false" <---- adjust this to false
redirectPort="8443"
acceptCount="10"
debug="0"
connectionTimeout="2000"
useURIValidationHack="false"/>
In addition i read that change JSP tomcat compiler by other faster like Jikes,
increase the general performance.
I'm installing Jikes at this time and i'm searching a better performance for my
system.
Other solutions that i'll try are:
- DB connection pool.
- Tomcat clustering with 2 servers.

Para: Tomcat Users List
Asunto: Speed of <jsp:useBean> tags.
Hello,
I have an application which is just a front-end for a main-frame. The process
on the mainframe which my application calls takes 8 seconds to complete so I am
trying to make my Java application as fast as possible so that there is as
little time as possible wasted.
Can anybody give any tips or sites for speeding up Tomcat/Java/Webapps?
Can anybody tell me if using <jsp:useBean> tags to pass an entire object to a
JSP is a slow way of doing things? Am I quicker passing a list of strings using
various request.setAttribute() methods? Or is this insignificant?
I am really stuck because I don't know how to choose the best way of going
forward. If I can't significantly improve the speed of the app. I should just
abandon the project but that is not desirable as you can imagine!
Andoni.
