Pit a few ruby methods against eachother, and chart it for great glory.
Props to the folks at Gruff (https://github.com/topfunky/gruff) for making this simpler to do, and to the Ruby team behind Benchmark.
We're going to need to define a chart.
c = Benchpress::Chart.new(
entities: {
string: -> { 'string' },
symbol: -> { :symbol }
},
min: 50_000, # Minimum times to run. Default: 0
max: 100_000, # Maximum times to run. Default: 1_000
step: 10_000, # Step rate for next benchmark. Default: 250
cycles: 3, # How many times to repeat, so as to get an average. Default: 1
name: 'string_vs_symbol', # File name. Default: 'Time.now.strftime '%Y-%m-%d-%H:%M:%S''
format: 'png' # File format. Default: png
)and then render it:
c.render # Line chart
c.render :line # Line chart
c.render :bar # Bar chart
Voila! Instant chart with realtime benchmarks to demonstrate complexities of methods everywhere! Supports an arbitrary number of entities.
Want something a tinge more beefy and realistic? How about parsing 9 megs of JSON?
c = Benchpress::Chart.new(
entities: {
oj: -> { Oj.load json },
json: -> { JSON.load json}
},
max: 10,
step: 2,
name: '9m-json-bar'
)
c.render :bar
