I have used same Hardware and OS platfrom for web server benchmarking and i have used similar php and jsp scripts for Apache and Tomcat. For this testing i have used apache ab benchmarking tool

From this statistics i would like to clarify the performances about Apache and Tomcat.

1. why Tomcat have taken too much of time to finish this 10 million requests to compare with Apache?
2. why this huge different for "Request per Second"?
3. To Tomcat i have increased multi thread level 300 and JVM memory usage upto 2048mb(but performances not increased), rather than these, is there any other performance tune-up settings for Tomcat?
4. from these statistics, can i come to the conclusion that apache is the best?
5.do u feel that ab tool favouring to Apache?
Welcome your opinions..

Thanks.
