Add performance graphs

@PikachuEXE Can you run the reports yourself and see if you see similar results? The dirk test make rabl/oj and jbuilder/oj look realy slow 🧐; I know it was faster when I made this gem, but I forget if it was that much faster

[PikachuEXE]

I don't think this makes me able to run the benchmark...

[malomalo]

Whoops yea, I was playing around with sizing of the graphs; need to add an option to analyzer somehow to set the size; will remove

Ruby 3.0.2

analyzer using latest commit to avoid the error

# Gemfile
gem 'analyzer', git: "https://github.com/malomalo/analyzer.git"

**performance/dirk/report.png**

**performance/rolftimmermans/report.png**

Yup the results looks really different from what we have in #4

I will post benchmark result run in 2.7 later

Ruby 2.7.4

analyzer using latest commit to avoid the error

# Gemfile
gem 'analyzer', git: "https://github.com/malomalo/analyzer.git"

Looks similar to 3.0 result...?

[malomalo]

Interesting, I wonder why there is a big difference now? I think the dirk test is a caching test no? Need to do some investigating....

[malomalo]

Added to the test suite over at joshmn/json-benchmark#27 as well; hopefully it gets pulled in.

[PikachuEXE]

Maybe trying reverting the version of rabl to what's available when #4 is submitted and retry?

Ruby 2.7.4
rabl 0.14.0 - released in October 31, 2018, see https://rubygems.org/gems/rabl/versions

**performance/dirk/report.png**

**performance/rolftimmermans/report.png**

Looks similar to previous one

Ruby 2.5.3
rabl 0.14.0 - released in October 31, 2018, see https://rubygems.org/gems/rabl/versions

Thoughts?
Other dependencies changed? Benchmark itself changed?

[malomalo]

Just tried some debugging to see what was going on. Nothing has helped.

The last think I can maybe think of is json gem performance regressions or patches for security; because the biggest hit was on the dirk test which is mainly a caching test. JBuilder needs to read cache -> convert to hash -> merge -> result. Does RABL do the same thing?

We could investigate more but all gems are up to date and we are getting similar results.... I'm okay just merging this in.

[PikachuEXE]

Does RABL do the same thing?

I have no idea as I have never checked their source code.
I am good for merging this as long as there is nothing wrong in our benchmark/setup/whatever.

Just one thing: Why your graphs have no legend and mine have?

[malomalo]

I can have some coworkers run it and see if they get the same results I'll merge.

re: graphs I was playing around with smaller output for the README
