Tuning Apache and MySQL for Best Performance in a Shared Virtual Hosting Environment
…raffic. For example, I have a server with Apache set to 256 maxclients, but the MySQL maxconnections set to 200, because many web requests do not require direct interaction with the MySQL server. Take a look at “Highest usage of available connections”, and lower maxconnections accordingly. It is safe to lower maxconnections to a number slightly above the reported highest usage. Doing so will allow you to set higher values for the indi… 19, 1, 2, 0 and 43.51
