6.4 Set the MaxClients Directive to a High value

You can let the HTTP Listener determine when to create more HTTPD daemons. Therefore, set the MaxClients directive to a high value in the configuration file (httpd.conf). However, you need to consider the memory available on the system when setting this parameter.

MaxClients=256 means that the listener can create up to 256 HTTPD processes to handle concurrent requests.

If your HTTP requests come in bursts, and you want to reduce the time to start the necessary HTTPD processes, you can set MinSpareServers and MaxSpareServers (in httpd.conf) to have an appropriate number of processes ready. However, the default values of 5 and 10 respectively are sufficient for most sites.
