caching - which machine should we use?


  we used since may the cern httpd 3.0 for caching (with about 20 
  accesses at the same time). in this month we want to expand our
  service to 300-400 accesses.
  does someone know how many performance one process of the cern httdp needs?
  has anyone expirience which machine we should use (buy) or should
  we use 2-4 server?

thanks in advance
