My experience with perl fcgi application is that you get maximum 
throughput when the number of fcgi processes is between the number of 
cores and 2 times number of cores on the system. For example if you have 
  2 QuadCore Xeons , that means that you get max throughput between 8 
and 16 fcgi proceesses.

I doubt that it will be very different with php+mysql.

Best regards
