Turned off all logging except error and crit. I will turn it ALL off and see
if that makes a difference.

I am testing the connection using two machines side-by-side; they use the
same network connection.

Think I optimized that one. I will check on it.

I will check on that possibility. Although the servlets are identical and no
one else is using my server setup yet; we are testing it before putting it
into production.

They are accessing the same database; if the problem exists in one, it
should theoretically exist in the other.

Optimized that to the following:
MinSpareServers 5
MaxSpareServers 10
StartServers 5
However, this is a special case. Because we are a startup and in deep alpha
development of the servlets, we only have about 100 users. I wonder if these
can be optimized more?

I will check out that program and run it against my server setup to test
speed. I may also need to rebuild Apache using a tighter config to install
only the modules that I need. My setup right now was built with mod_so; from
what I have heard, mod_so can be a speed hit due to its size.

Wow! Thankfully, I have only Apache and Jserv to deal with, although I will
be testing Tomcat soon.

You would have to ask my boss first!
Merci Beaucoup! <--Hope that is spelled right!
