I managed to configure the tomcat proxy behind my apache 2.2 worker threads
not to crash anymore, but still it stutters, while I observe the following
conditions on my high load, complex site:

When the users come in with 500-1500 request/second the apache process
collects the incoming request within reading state "R", as viewed
by "server-status".

The bigger I make the apache thread configuration the heavier seems the impact
on the tomcat behind mod_proxy (HTTP connector).

So lets talk big: The apache process collects about 1000-5000 requests when
the tomcat manages to start working, removing the requests from the queue.

When it started working it is even able to reduce the pending requests to a
few 5-20, which is nothing of course. But the users already come in again
and start populating the queue of the apache reinventing the stuttering
condition.

Are there any hints how I can configure the tomcat/apache team to stop this
condition ?

May prefork or a smaller worker configuration help the tomcat to react (apache
config) ?

Are there possible tunings in web.xml, server.xml or other paramters that help
me to react on requests faster ?

May it help to drop the apache in front at all, giving the tomcat even more
requests of course, since it has to answer to the static contents too ?

Any hints will help.

TIA

bye ingo
