Thank you for your help. I found some interesting information in the server stats.

Can you please tell me what does contain the column CPU? I thought it is the percentage of CPU usage, like the commands top and ps show, but I've seen even a number like "1468.634" in that column, so it should be something different.

Thank you.

Have you tried using the Apache stats?

In /etc/httpd/conf/httpd.conf

 ExtendedStatus On
 <Location /server-status>
   SetHandler server-status
   Order deny,allow
   Deny from all
   Allow from .your.domain
 </Location>
 <Location /server-info>
   SetHandler server-info
   Order deny,allow
   Deny from all
   Allow from .your.domain
 </Location>

In /etc/httpd/conf.d/perl.conf (or similar)

 <Location /perl-status>
   SetHandler perl-script
   PerlResponseHandler Apache2::Status
   Order deny,allow
   Deny from all
   Allow from .your.domain
 </Location>


Then browse to get more information
http://your.server/server-status
At a peak busy time look for Apache children with a 'W' in the 'M' column.
These are busy working and show you what is tying up your server.

Also
http://your.server/server-info
Apache config
http://your.server/perl-status
Perl config

Depending on what's using your Apache time up, you may get better
performance by compiling a lightweight frontend Apache that serves static
files and proxies application requests to a backend Apache compiled with
mod_perl.
