<H2>Summary</H2>
|
|
|
|
<p>This Multi-Processing Module (MPM) implements a pre-forking
|
|
non-threaded web server which handles request in a manner
|
|
very similar to the default behavior of Apache 1.3 on Unix.</p>

The MaxSpareServers directive sets the desired maximum number of <EM>idle</EM>

child server processes. An idle process is one which is not handling
|
|
a request. If there are more than MaxSpareServers idle, then the parent
|
|
process will kill off the excess processes.<P>

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.<P>
