Can you disclose what monitoring tool you use and explain how it
impacted the measured value?
Interesting. What monitoring tool are you using?
The monitoring tool used is Introscope from CA. You need to pay attention
to the Deep Inheritance parameter.
And, did it make a difference?
Hi Christopher,
Thank you for your contribution to this thread. I think we we have made
good progress on the subject, here are some elements i'd like to share :
- The fact that the response time was increasing with the the number of JSP
loaded was linked to our monitoring tool... This tool
Hi Sylvain,
thank you for sharing all these details!

This thread is bit old, but there were no conclusions si I figured I'd
pick it back up.

Can you post the contents of your JSP?
No, i can't publish the code of this JSP.
So what is your point?
Nothing specific, i just answered the question, we hadn't this problem when
the application was running of Websphere.
Right now i give priority to a scenario where the PermGen is large

Hi,
I'm facing performance issue with my application which loads a very large
number of different JSPs (ie 16 000). As the application loads the
different JSP, the response time becomes longer and the CPU increases.
I have tried many configurations by modifying the
16000 objects
co-existing at the same time unused which is overloading the server.
Any suggestions/remarks ?

Yes, don't top-post.
So I'll move you, to show you how it's done here.

Hi,
I am not very sure . But I guess If we consider the servlet lifecycle the
servlet is not supposed to get instantiated until requested for .
The question is, do the JSP pages contain static text or JSP

Hi,
Thank you all for your returns.
Maybe also, just to give us an idea, you could tell us how much memory that
system has, and how much is given to use by Tomcat ?
Xmx is 1500 Mo. The PermSize is set so that it can easily load the max
number of JSP set with the maxLoadedJsp (set to 5000)

4. Here is the behaviour that i observed : i request the URL of a jsp in a
loop. The content of this JSP is always the same but it's name is different
in each URL so that it is considered as a new one.
