Web Appliction Performance Optimization:

• download production db and recreate in development
• use profiling tools to figure out where your application is slow
• make the thing faster
• optimize the code parts of the application
  • query review (tools / mysqlslow log)
  • decide what's slow (no limit / no index / table scan ... )
• optimize the front-end part
  • javascript (externalize / position / minification / consolidation)
  • css (position / minification / consolidation)
  • http pipelining request limit per domain (create multiple subdomains)
  • big stuff? use a CDN (Akamai / Amazon Cloudfront / Limelight)
• optimize the server part
  • set up your cnames / aliases for asset hosting
  • mod_expires
  • mod_gzip
  • etags (off!!!)
• other tools
  • benchmarking (ab / httperf / jmeter / ...)
