[rt-users] Max performance suggestions on slow hardware?

[AJ]

Also pay close attention to mysql's memory usage.  On linux mysql spawns a
child mysqld process for every connection.  A good place to look is in the
<mysql_home>/support_files and there are several example cnf files.  If you
have a box with little memory, consider the my-small.cnf

Also lowering the connection timeouts can help as well.

IT would probably pay to reduce the number of concurrent apache
processes in low memory situations. Also, it's worth making sure your
MTA knows not to fork off delivery processes if load is skyrocketing.
