22. Processing #

23. Don’t be a smart-ass “Oh, I know, we have to

    cache it!”

24. Measure gem 'ruby-prof'
 gem 'rack-mini-profiler'

25. Measure in production mode pre-production stage

 gem 'skylight'

27. Measure profile - focus on the slowest part

28. Measure benchmark - compare alternative solutions

29. Improve

30. Improve Rely on your database

31. Improve Where is your cache?

34. Improve When needed - mutate

35. Improve Upgrade your libraries

36. Improve When needed - replace your libraries

37. Improve gem 'json'
 
 gem 'oj' gem 'oj-mimic-json'

38. Improve Native extensions - not only C!

49. Speed up your API use CDN infrastructure profile and benchmark

    focus on the slowest part rewriting is the last thing to consider

50. Speed up your API Ruby is fast enough Sinatra is

    fast enough Rails is fast enough
