Subject Just another Benchmark
Date Fri, 02 Mar 2001 09:50:29 GMT
Hi,

we tried the apachebench on our solaris system, to check out
differences between architectures and thereby we found a quite
interesting behaviour.

When serving a static page, apache uses the whole machine
resources while tomcat isn't (CPU usage 100% to 20%) and for
maybe this reason isn't serving at the same speed as apache.
Is there a limit somewhere in the java net or in tomcat?

We used apachebench with 'ab -c 10 -n 50000
Config:
apache with mod_jk, and ajp13 to tomcat.
Solaris 8

regards, tom
