Hi Andy,
What are times like in your logs?
Is each request slow or is it just that you get so many?
Try attacking the problem from the client side too.
Using Firefox with firebug or Chrome with it’s developper tool could tell you
more.
You might see if the requests spend most of their times resolving dns for
instance, or waiting for redirection etc.
Keep digging. Premature optimisation will not help you if it’s not applied to
the root cause of your problem.
Also, try to get some data using mod_status, especially how many connections
are open at any given time.
Shame you are not running 5.1 or later.
The new dashboard was created especially for this kind of problem.

Lastly, we don’t use the worker module.
We are running apache in prefork mode (threads are not used).
The server limit you have set is very low.
This is what you were looking for:
$Timeout = "5";
$KeepAliveTimeout = "3";
$MaxClients =
pf::services::manager::httpd::calculate_max_clients(pf::services::manager::httpd::get_total_system_memory());
$StartServers = "4";
$MinSpareServers = "2";
[in conf/httpd.conf.d/httpd.portal]
Let us know what you find.
