Godfrey Chan f2f9b88685 Introduce a benchmark template [ci skip] ... This replaces boilerplate in the “benchmark your code” section of the contributors’ guide with an executable template. I also amended the text to encourage best practices and codified it in the template. For now this is only good for relatively self-contained changes that can be inlined into a simple script. In the future, this can be expanded to cover how to measure the difference between two commits. The output looks like this: ``` ==================================== Empty ===================================== Warming up -------------------------------------- blank? 225.963k i/100ms fast_blank? 238.147k i/100ms Calculating ------------------------------------- blank? 8.825M (± 6.4%) i/s - 44.063M in 5.014824s fast_blank? 9.311M (± 6.3%) i/s - 46.439M in 5.009153s Comparison: fast_blank?: 9310694.8 i/s blank?: 8824801.7 i/s - same-ish: difference falls within error ================================= Single Space ================================= Warming up -------------------------------------- blank? 56.581k i/100ms fast_blank? 232.774k i/100ms Calculating ------------------------------------- blank? 813.985k (±16.7%) i/s - 4.017M in 5.076576s fast_blank? 9.547M (± 5.2%) i/s - 47.719M in 5.013204s Comparison: fast_blank?: 9547414.0 i/s blank?: 813985.0 i/s - 11.73x slower ================================== Two Spaces ================================== Warming up -------------------------------------- blank? 58.265k i/100ms fast_blank? 244.056k i/100ms Calculating ------------------------------------- blank? 823.343k (±16.2%) i/s - 4.020M in 5.014213s fast_blank? 9.484M (± 4.9%) i/s - 47.347M in 5.005339s Comparison: fast_blank?: 9484021.6 i/s blank?: 823343.1 i/s - 11.52x slower =============================== Mixed Whitspaces =============================== Warming up -------------------------------------- blank? 53.919k i/100ms fast_blank? 237.103k i/100ms Calculating ------------------------------------- blank? 763.435k (±16.8%) i/s - 3.720M in 5.018029s fast_blank? 9.672M (± 5.8%) i/s - 48.369M in 5.019356s Comparison: fast_blank?: 9672467.2 i/s blank?: 763435.4 i/s - 12.67x slower =============================== Very Long String =============================== Warming up -------------------------------------- blank? 34.037k i/100ms fast_blank? 240.366k i/100ms Calculating ------------------------------------- blank? 409.731k (± 8.9%) i/s - 2.042M in 5.028235s fast_blank? 9.794M (± 4.3%) i/s - 49.035M in 5.016328s Comparison: fast_blank?: 9794225.2 i/s blank?: 409731.4 i/s - 23.90x slower ```		2016-10-15 12:34:46 +02:00
