What are the best practices for configuring the httpd.conf file in Apache to optimize CPU usage and performance?

To optimize CPU usage and performance in Apache, it is important to carefully configure the httpd.conf file. Some best practices include enabling caching mechanisms, setting appropriate KeepAlive settings, adjusting the MaxClients value to match server resources, and utilizing compression techniques like mod_deflate. ```apacheconf # Enable caching EnableMMAP off EnableSendfile off # Set appropriate KeepAlive settings KeepAlive On KeepAliveTimeout 5 # Adjust MaxClients value MaxClients 150 ServerLimit 150 # Utilize compression LoadModule deflate_module modules/mod_deflate.so AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css ```
