Benchmarks

Riverboat is faster than

• chehsunliu/poker
  • by 1.7x for 5-card evaluation
  • by 1.2x for 6-card evaluation*
  • by 1.4x for 7-card evaluation*
• notnil/joker
  • by 325x for 5-card evaluation
  • by 150x for 6-card evaluation*
  • by 74x for 7-card evaluation*

^{_{*Riverboat and notnil/joker's 6- and 7-card hand evaluation are not directly comparable to chehsunliu/poker's, as Riverboat and Joker return both the best 5 cards, as well as their absolute ranking, whereas Poker only provides the absolute ranking.}}

All benchmarks were measured over the same set of cards, and the timing did not include the conversion of cards from human-readable string form to native representation.

This benchmark was run on a 2018 Macbook Pro with an Intel i9-8950HK 2.9GHz processor. The precise benchmarks run can be found in benchmarks_test.go
