Hi All, As I mentioned in my previous email I was able to get my system performance using Apache-Tomcat-Jre1.6 such that I was getting 4msec transaction response times. My problem is I can not tell how much of that response time is spent in tomcat versus Apache. I am using windows 2000 where the configuration is Apache - (Tomcat embedded in JBoss 4.2.1) using Mod_jk. The problem I can measure the transaction in the servlet which is in the sub-microsecond range but at apache access logs or in the mod_jk logs I am seeing either 0 or 15msec. I suspect that is due to the timers used by Apache. I would like to know how long Tomcat is taking for the request. I am using web services inside of Tomcat so the request goes through that layer. Also, can anyone tell me the performance differences they have see when Tomcat is running on Linux versus Windows? I have heard anything between 1 to 30% improvment. Also, any hints on how to improve Tomcat performance appreciated.
