[users@httpd] Right Server Process Params for High Traffic Site

[Alex Menendez <am...@mail.monkeybrains.net>]

Hello, 

I help run a site of about 3.5 million page views a day.
We currently run apache 1.3.X with mod_perl and are switching to
a dual apache HTTP accelerator architecture. 

We plan to put apache2.0 in the front serving static files and proxying 
mod_perl requests to our current heavy apache servers listening on the 
loopback. 

We are using solaris and I have been testing the new architecture with the 
worker mpm. It seems to work great in test. However, I am not really sure 
how to configure a multi-hreaded/multi-process apache for our high traffic.
Our cluster consists of 8 servers. Our current apache1.3.X server are 
configured with huge serverlimits which seems to hold up fine. 

But what do I do with apache2.0? are there any rules of thumb? 

I currently have the following default settings for my test server:
StartServers         2
MaxClients         150
MinSpareThreads     25
MaxSpareThreads     75
ThreadsPerChild     25
MaxRequestsPerChild  10000 

How do I optimize these for my production env of 3.5 million page views 
across 8 machines? 

any advise here would be greatly appreciated. 

regards,
 -amen
