Subject RE: Tomcat problem on a multiple CPU system
Date Mon, 05 May 2008 11:42:34 GMT
I think I found the problem, but not the solution :(

I have the same problem on my local 2 cpu computer, if I start Tomcat in
server (-server) mode I have exactly the same problem, i.e. Tomcat
doesn't want to use all CPU resources.. If I start my Tomcat in client
(-client) mode, my processes run faster by using 100% of all CPU...

But, my server is 64 bit, I'm using all the 64 bit stuff, and JDK 1.5
and 1.6 can only be started in server mode... But I still don't
understand why it's fast without Tomcat even in server mode since this
is the default and only one mode...

Use ieHttpHeaders, the AccessLogValve or similar to check when the
requests 
are actually being sent. I suspect that, as David suggested that you
have 
no more than two requests running in parallel.

You can tweak the registry to increase the concurrent connection limit
or 
use a test tool like JMeter to increase the number of parallel requests.
