Basic Ruby 2.0 benchmarks calculating pi from gist [1] $ ruby --version ruby 1.9.3p385 (2013-02-06 revision 39114) [x86_64-darwin12.2.1] $ time ruby pidigits.rb 10000 2>&1 > /dev/null 17.51s user 0.11s system 99% cpu 17.639 total $ ruby --version ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-darwin12.2.1] $ time ruby pidigits.rb 10000 2>&1 > /dev/null 4.64s user 0.27s system 99% cpu 4.927 total That's a significant difference in speed. Going from 17.51 seconds to 4.64 seconds 1. https://gist.github.com/thoughtpolice/5025417 [github.com]
I've also seen a speedup in Rails app boot time (the require optimizations): 1.9.3-p194: 11.8s 1.9.3-p385: 9.9s 2.0.0-rc2: 6.1s! Tests were done with `time bundle exec rake environment` 5 times, dropping the highest and lowest and getting the mean of the rest (lazy snow day benchmarking). Very exciting!
どれくらい速くなったんだろ (スコア:0)
RPythonで実装したら本家より断然速いぜってニュース最近見た気がするけど
本家も徐々に速くなってんですよね？
Re:どれくらい速くなったんだろ (スコア:2, 興味深い)
「性能改善」として記載されている通り、速くなっているところもあるみたいよ。

個人的にはRails 4がリリースされてから検討だなあ。
