[edit] Performance
Benchmarks by rubychan.de showed significant increases in performance.[1] Benchmarks by Antonio Cangiano showed an an average four times speed improvement over the existing interpreter.[2] Both evaluations comprised a mix of mostly synthetic benchmarks.
Ruby on Rails was reported to run about 15% faster with YARV compared to Ruby 1.8.6.[3]
[edit] History
On January 1, 2007, YARV was merged into the Ruby Subversion repository.[4]
Ruby creator Yukihiro Matsumoto fully merged YARV into the Ruby 1.9.0 version which was released December 26, 2007.[5] From this point onwards YARV became the official Ruby interpreter, replacing the one developed by Matsumoto.
