Apache Max Client

[Mac]

Can someone tell me about the "Max Client" in Apache? How that effects traffic or bandwidth?

Thanks, mac

Read this:
http://httpd.apache.org/docs/2.0/misc/perf-tuning.html
and this http://httpd.apache.org/docs/2.0/mod/mpm_common.html#maxclients
--------------------
In a nutshell:
The MaxClients directive sets the limit on the number of simultaneous requests that will be served. Any connection attempts over the MaxClients limit will normally be queued, up to a number based on the ListenBacklog directive. Once a child process is freed at the end of a different request, the connection will then be serviced.
