The JSP's are not precompiled, but the performance test is repetitive over 10 minutes and has a "warm-up" period. the web stress tool has 100 client threads run, each making variety of requests (exercising the whole app) as fast as the server allows. The problem is not with Tomcat - it performs impressively with it's own http connector (500 rps with a 1.6Mhz Celeron), but rather with the jk connector combo. I would be interested to hear from others who have benchmarked apache-->tomcat against tomcat standalone performance.

Also take out everything your not using in server.xml (http) etc. That might pick things up a bit. Are your jsp's precompiled? rls "David Tildesley" <[EMAIL PROTECTED]> 10/29/2002 12:02 AM Please respond to "Tomcat Users List" To: "Tomcat Users List" <[EMAIL PROTECTED]> cc: Subject: RE: Apache 1.3/2 mod_jk connect Tomcat 4.1.12 on redhat7.3 - poor perf No, it isn't. I now strongly suspect this is the penalty when using the JK connector. -----Original Message----- From: Sexton, George [mailto:gsexton@;mhsoftware.com] Sent: Sunday, 27 October 2002 5:25 a.m. To: Tomcat Users List Subject: RE: Apache 1.3/2 mod_jk connect Tomcat 4.1.12 on redhat7.3 - poor perf As a guess, is Apache resolving host names for the logs? -----Original Message----- From: David Tildesley [mailto:datil@;paradise.net.nz] Sent: 25 October, 2002 8:06 PM To: [EMAIL PROTECTED] Subject: Apache 1.3/2 mod_jk connect Tomcat 4.1.12 on redhat7.3 - poor perf Has anybody any tips for performance tuning Apache 1.3 or 2 connected to Tomcat 4.1.x via mod_jk (couldn't get mod_jk2 working)? We had a throughput for our servlet/jsp app of 500 rps (requests per second) on tomcat http connector. As soon as we connected Apache to Tomcat, the rate dropped to 150 rps for no apparent reason. Any advice on how to improve this performance?
