Ways to improve performance

Static compile a minimum of modules

Pick the right MPM and configure it

Persistent connections

  KeepAlive On
  KeepAliveTimeout 
  MaxKeepAliveRequests
  (TimeOut)

Reverse DNS lookups

  HostnameLookups Off
  Allow/Deny (use IP addresses)
  ServerName
  (UseCanonicalName)

Logging
  - avoid as much as possible!

.htaccess files

  <Directory />
    AllowOverride None
  </Directory>

Keep httpd.conf small

Memory mapping of static content
  Module: mod_file_cache
  MMapFile /users/2012/dtab2/CS2510/htcodc/images/logo.gif

Memory mapping of file handles
  Same module
  CacheFile /users/2012/dtab2/CS2510/htcodc/images/logo.gif

Dynamic content
  - employ better programmers
