What kind of load according to what?
Behaves badly how?

Since you choose not to answer most of my questions I assume that you 
are not actually interested in getting help with the problem, but I'll 
give you a short a comment to the only answer you gave:

If you have your application code running in the http processes, such as 
PHP or mod_perl code, it could well be that code wich takes a lot of 
recourses rather than Apache itself. But since you choose to withhold 
that information from us, we can't even guess...

No, that's not correct.

Please read the docs at, where the above directioves 
are explained. If you don't understand the docs, then come back here for 

Also, the total amount of simultaneous users is *not* the same as total 
amount of simultaneous connections. HTTP is stateless and request 
oriented, not connection oriented.

In many systems the amount of simultaneous users can be way more than 
the amount of simultaneous connections, but in systems where most pages 
and even images are dynamically and slowly generated it may well be that 
the amount of simultaneous connections is sometimes way higher than the 
amount of simultaneous users.
