Hi,
I'm not sure if this will apply in your case, but I found that
offloading the mail to a second (relatively low spec as it happens)
local machine improved the mail output rate considerably - mailouts went
in about 1/4 of the previous time.
The local mail server was using CPU cycles and the servlet app using
lots of memory in our case - combined on one machine the overall load
rocketed and the web app seemed to suffer most.
Not exactly the answer you were looking for I guess, but tinkering with
the connector attributes didn't actually seem to make a great deal of
difference to us.

Sorry I forgot to add:
<Connector port="8009" protocol="AJP/1.3"
connectionTimeout="20000"
enableLookups="false"
redirectPort="8443" maxThreads="300"/>
We also run under SSL, which is taken care of by Apache.

Subject: Tomcat Production Configuration
Hi All
My question concerns optimizing Tomcat.
Our setup is roughly this:
- Dual Quad Core with 8 gigs memory (4 gigs dedicated for Tomcat)
- Single instance of Tomcat6
- Single web application (Java Servlet)
- AJP connector
A little about the application:
The site is relatively low volume, however traffic spikes when our newsletter
is sent out. The application is complex and connects to a large research
database serving a number large pages with reports, charts, data tables etc,
which are generated dynamically from live data... sessions tend to get quite
large. My thinking is that I should be supporting in the region of 200 to 300
sessions as a minimum.
So given this setup, how should I configure the connector with regards to:
maxThreads and any other relevant attributes. I am thinking of about 300
threads? I would be grateful for your advice.
Thanks for your help,
Peter
