- 12. Previous performance efforts • Identified some slow requests, handful of obvious problems - Improve SQL performance (better performing queries, add indices, etc.) - Fix inefficient code • Rewrite serialization code to be more performant, return less data • Tech updates: upgraded some of our core libraries (Rail version upgrade, Ruby upgrade) • JavaScript Performance - Split JS files into “modules” - More cacheable by CDN - Eliminated 3rd party CSS/JS libraries that were not being used much - Eliminated as much “onload” JS as possible - Improved JS loading
