•Time per request
When testing different parameter settings for the httpd.conf, use these values to compare and find the best configuration setting for your system.
MaxRequestsPerChild
The MaxRequestsPerChild directive sets the limit on the number of requests that an individual child server process handles. After the number of requests reaches the value set for the MaxRequestsPerChild parameter, the child process dies. If there are no known memory leaks with the IHS version, set this value to zero (0) to specify an unlimited amount.
LoadModule and AddModule
The more additional modules are loaded by IHS the more memory is consumed per process. Therefore, turn off the loading of all unnecessary modules. Consult http://httpd.apache.org/docs/mod/ for detailed descriptions on the different modules.
Timeout
This parameter specifies the number of seconds before sends and receives time out. The recommended value is 180.
Listen
On servers configured with multiple network interface cards (NICs), use the Listen parameter to specify which IP addresses and ports IHS should serve. For example:
Listen 127.0.0.1:80
Listen 127.0.0.1:8008
Listen 192.168.56.1:80
Listen 192.168.130.1:80
ServerTokens
This parameter controls which information about IHS is sent back to the client with the header of the HTTP response. For security reasons, it is recommended that you set it to the following:
ServerTokens Prod
This will respond with the product name only and will not send information about the version number or the installed modules.

Adjust the following IBM HTTP Server properties and parameters in Windows 2000 to tune your server performance.
ThreadsPerChild
This parameter sets the number of concurrent threads running at any one time within the IBM HTTP Server. Set this value to prevent bottlenecks, allowing just enough traffic through to the application server.
Use the following procedure to change this parameter:
1.Edit the IBM HTTP Server file httpd.conf located in the directory
IBM_HTTP_Server_root_directory/conf.
