Web Performance Analysis & Optimization tools
[Update:26-Dec-2016] - I got a chance to revisit the tools I listed below six years ago. I'll leave the original list as it is but below are what I would try in the future as they are extremely convenient to use -
- Chrome Developer Tools, Audit tab (F12 keyboard shortcut)
- Google Page Speed
- Web Page Analyzer
- DOM Monster
1. Run all the free perf tools to study the issues pointed out by them
2. Consolidate them based on which are serious & workable (not all suggestions may have easy fixes & there has to be a trade-off between usability, maintainability, security, SEO, cost & performance)
3. Make modifications & measure continuously
