The Group value corresponds to the Group directive. The Group directive is similar to the
User directive. Group sets the group under which the server will answer requests. The de-
fault group is also apache.
13.5. Performance Tuning
Click on the Performance Tuning tab to configure the maximum number of child server
processes you want and to configure the Apache options for client connections. The default
settings for these options are appropriate for most situations. Altering these settings may
affect the overall performance of your Web server.
Figure 13-14. Performance Tuning
Set Max Number of Connections to the maximum number of simultaneous client requests
that the server will handle. For each connection, a child httpd process is created. After this
maximum number of process is reached, no one else will be able to connect to the Web server
until a child server process is freed. You can not set this value to higher than 256 without
recompiling Apache. This option corresponds to the MaxClients directive.
Connection Timeout defines, in seconds, the amount of time that your server will wait for re-
ceipts and transmissions during communications. Specifically, Connection Timeout defines
how long your server will wait to receive a GET request, how long it will wait to receive TCP
packets on a POST or PUT request and how long it will wait between ACKs responding to
TCP packets. By default, Connection Timeout is set to 300 seconds, which is appropriate for
most situations. This option corresponds to the TimeOut directive.
Set the Max requests per connection to the maximum number of requests allowed per per-
sistent connection. The default value is 100, which should be appropriate for most situations.
This option corresponds to the MaxRequestsPerChild directive.
If you check the Allow unlimited requests per connection option, the
MaxKeepAliveRequests directive to 0, and unlimited requests are allowed.
If you uncheck the Allow Persistent Connections option, the KeepAlive directive is set
to false. If you check it, the KeepAlive directive is set to true, and the KeepAliveTimeout
directive is set to the number that is selected as the Timeout for next Connection value. This
directive sets the number of seconds your server will wait for a subsequent request, after a
