  Did you compile Apache to do more than the internal limit of 250 ?  
  If so, then try this basic formula -

  Amount of RAM per httpd times the number of httpd equals the amount 
  of RAM for concurrent connections.

  CPU usage is more based upon how much swapping you do versus how 
  much Network I/O you do...
