NOPE!! Using Linux 6.1 RH

I understand that there will be a performance degradation when tag
libraries are used.But still the same page must be in the
same range right??
>3. deeply nested try/catch statements result in rapid performance
degredation under load



Well, maybe i need to check the tag''''''''s code for nested try/catch
I don''''''''t remember adding any, anyway will check this.

try/catch. Also, tomcat 4.0.4 has a new httpconnector called coyote.

Maybe I will try with 4.0.4& 4.1.3

But using includes/forwards will increase the performance load, rather
than decreasing it. B''''''''cos the request handler has to process
the request and there is always an overhead in using includes

NOPE!!! just tomcat.
I have even removed all other web applications, since they affect
the performance of tomcat.
