Why after increasing the value of "MinSpareServers" server load increased?

Solution Unverified - Updated -

Environment

  • Red Hat Enterprise Linux 5.7
  • httpd-2.2.3-53.el5_7.3

Issue

  • Why after increasing the value of MinSpareServers server load increased?

Resolution

  • If you want to set the value of MinSpareServers to 1000 to mantain the high traffic load but in normal situation increase in the MinSpareServers to a large number is unnecessarily creates a heavy processing load on the server.

  • The MinSpareServers directive sets the desired minimum number of idle child server processes.

  • An idle process is one which is not handling a request. If there are fewer than MinSpareServers idle, then the parent process creates new children at a maximum rate of 1 per second.

  • Tuning of this parameter should only be necessary on very busy sites. Setting this parameter to a large number is almost always a bad idea.

  • It is always suggested that as per the requirement you have to tune it for your apache server but not necessarily to 1000.
