title: web server maximum number of users apache can handle?
body: <p>My question is what is the maximum number of users that Apache webserver 2.2.2 can handle, i have a website which sometimes gets over 300+ concurrent users, however apache default configuration is set to max 150, i know i can increase this value, however if i do i fear that i might run over the capacity that Apache can handle, my server is quite powerful with 8 quad core AMD processor with 16 GM memory </p>
  
  <ol>
  <li><p>How do i determine how many requests that apache can handle,</p></li>
  <li><p>In general what the options/configurations for a best optimised for server loads. i.e disable keep alive ..etc</p></li>
  <li><p>When i increase the max user size , MySql eats up most of the processor power with going over 150% CPU sometimes .... not sure why ..</p></li>
  </ol>
  
  <p>Any experts ?</p>
