Configuring Apache for Maximum Performance LG #123
This guide explains how to optimize Apache web server performance on Linux systems through compile-time and runtime configuration adjustments rather than hardware upgrades. Key recommendations include loading only necessary modules, selecting appropriate Multi-Processing Modules, disabling DNS lookups, tuning process limits (MaxClients, MinSpareServers, MaxSpareServers), enabling HTTP compression via mod_deflate, and implementing client-side caching headers. The author also advocates for a split-server architecture using a lightweight front-end Apache to serve static content and forwarding dynamic requests to a heavier back-end server, which prevents memory waste from large processes handling small static files.
