- 102. #velocityconf Using server-side ads code over client-side ads code saved us ~20% of page load time 20%
- 104. #velocityconf • Last mile acceleration (use GZip compression) • Take advantage of a CDN, if possible • Only use cookies where necessary • Caches are your friend Server and back-end
- 106. #velocityconf • Decide on the server what to serve • Different websites (Text, Rich, Touch) for optimized experience • Optimized and different images for all of our 3 mobile sites • Edge side include technology (ESI) for device detection and/or conditional loading Server-side optimization & device detection

- 123. #velocityconf Improvement is easier than you think
- 124. #velocityconf • Re-factored code: Removed old/un-used code • Moved some scripts to the bottom of page • Minified and concatenated scripts and CSS files to reduce file size and HTTP requests How did we improve
- 125. #velocityconf Why optimizing manually if you can automate it? Included performance optimization into your deployment and release process
- 126. #velocityconf • Maven, Ant Tools and Plugins • Closure Compiler (Google) • Minify-maven-plugin • HTMLCompressor • Confess • cssembed.jar or compass for data:uri Automated & built-in tools
- 127. #velocityconf • If you can’t / don’t want to use Maven / Ant • You should use taskrunners and scaffolding: Grunt, Yeoman • Continuous integration (e.g SPOFcheck, yslow) Automated & built-in tools
