Inspired by The Crystal Language from ~scratch~ ruby by Sérgio Gil presented on Ruby Unconf 2018.
It seemed that crystal is quite easy to try for people who are used to ruby.
So, let's compare Ruby(grape) to Crystal(kemal) performance, ease of use and programmer happiness =) ... or at least some of the previous =D
static:
{"hello":"dolly"}
random (where the number is generated using rand(365)):
{"your_happy_number":203}
Despite default behavior without any performance optimizations was initially aimed. Few adjustments were tried on grape.
All data were measured on same computer with ab with same params (-n 1000 -c 6)

Some say oj is great for handling JSONs, I expect they are fast in parsing, but purely for outputting it does not seems to bring much difference
