Hi,
I know that Tomcat does not claim to strive for the performance
characteristics of other servlet containers, such as resin. However, I am
wondering just how bad the performance is. I have run some tests, and I have
been a bit surprised.
Test environment is a 4 proc NT server with 1 gig of memory. I am using
tomcat 3.2.1 running standalone, and have set the max heap size for the JVM
to be about half of physical memory, also I have the server hotspot jit
installed.. Additionally I am using Jmeter to apply some load.
With 1 Jmeter client configured with a standard delay of 1 ms and 20
threads, the website being hit becomes essentially non-responsive. Using the
same configuration, but substituting resin for tomcat, shows no noticeable
degradation in performance.
Again, I am not surprised that resin performs better, but I am surprised
that Tomcat is that much slower, with even a light load applied.
Are these performance characteristics to be expected. Does these results
surprise anyone.
Any feedback would be appreciated, and thanks in advance.
