Hi, Sorry mail client got corrupted, so just copied your mail and see inline for answers
For Peter: >Are you using tomcat 4.0.3 _ jdk1.4 on Solaris? NOPE!! Using Linux 6.1 RH >1. pages with lots of tags (50+) do not perform well under load >2. pages with 100+ tags may not compile due to 64K per method limitation >in Java. This particular issue is currently being address by a couple >developers and should be fixed in 4.1.x. 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. >There are a couple things that will improve the situation. When tomcat >4.0.4 comes out, it has a recent patch which fixes deeply nested try/catch. Also, tomcat 4.0.4 has a new httpconnector called coyote. >Together the performance improves dramatically such that the number of >concurrent requests triples. Also, the response time improves Maybe I will try with 4.0.4& 4.1.3 >significantly. If you''re page still performs poorly, try breaking it up >into include files and use action include instead of include directive. >I.e use <c:import> or <jsp:include>, instead of <%@ include %>. I hope >that helps. 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 > >peter Euclides:(thought i sent it not sure so just reposting) >Hi. It seems very strange. you ve got very differents response time, from 90 >up 2200 ms!!! Do you have any other kind of service running and wasting your >cpu or io service? NOPE!!! Just tomcat. I have even removed other web applications b'cos they seem to affect the performance of tomcat. >Regards, Euclides.
