[jruby-dev] [jira] (JRUBY-6684) Performance degradation: Slim benchmarks

[Kevin Menard (JIRA)]

Kevin Menard created JRUBY-6684 Performance degradation: Slim benchmarks Issue Type: Bug Affects Versions: JRuby 1.7.0.pre1 Assignee: Unassigned Components: Performance Created: 25/May/12 7:02 AM Description: Slim (https://github.com/stonean/slim) comes with a nifty rake task for benchmarking erb, erubis, slim, and haml against each other. I decided to see what the impact would be between JRuby 1.6.7 and JRuby 1.7.0-preview1. As it turns out, JRuby 1.7.0-preview1 is roughly 3x slower than 1.6.7 and 2x slower than MRI 1.9.3-p194. To run the benchmarks, clone the linked git project and run "rake bench iterations=10000". The output I'm seeing is: JRuby 1.6.7 Rehearsal --------------------------------------------------- (2) erb 1.636000 0.000000 1.636000 ( 1.636000) (2) erubis 0.843000 0.000000 0.843000 ( 0.843000) (2)
