That's not very good advice.

If apache is the only thing running on the box, then you should set
MaxClients to the highest number that the system can handle in
physical memory.  You need to be sure to restrict MaxClients to
prevent apache from ever using so much memory that the system starts
to swap, since your performance will get killed.

If you are running other services on the box, then you obviously need
to set MaxClients to a lower number to allow those other services to
have resources.
