18. DO: 32GB droplet, 12 cores!
19. 39 req/s x 6?! 2 cores => 12 cores! ~10x faster?!
20. ! requests=1000, concurrency=500! ! Requests per second: 58.84 [#/sec] (mean) 5.2x faster!!

27. CACHE EXPIRY?! !1
29. Purge everything Purge by key Purge by URL
30. Purging by key headers[‘Surrogate-Key’] = “product_id=1” headers[‘Surrogate-Key’] =! “product_id=1 taxon_id=1 taxon_id=2”! !
31. Purging URLs /api/products! ! /products/ruby-on-rails-tote
