How to enable Apache compression with mod_deflate

Apache comes standard with the mod_deflate module that enable you to compress the content of web pages before they are sent over the wire. Please note that you should probably disable other compressors (like PHP compression, if enable) before using the Apache compression feature.

To enable compression under Apache with the module mod_deflate, please follow these instructions:

ThreadsPerChild MaxRequestsPerChild

This directive sets the number of threads created by each child process (1 for Windows).
The child creates these threads at startup and never creates more.
ThreadsPerChild 256 (default is 64)

Limit on the number of requests that an individual child server will handle during its life.
MaxRequestsPerChild 0 (This is the default value on Windows)
