Ruby 1.9.2 RC2 is released
- philwelch 16y agoIf you're on Ruby 1.9.1 and want to use Rails 3 Beta 4, you have to upgrade to 1.9.2 or the new Rails beta won't work.
- sigzero 16y agoI have not looked at the Ruby side in a while. I know the 1.8 series put Ruby as one of the slowest of the dynamic language but vaguely remember that being worked on. Had 1.9.X brought a good speed improvement?
- texel 16y agoThere are a lot of projects aiming to fix that, but yes, YARV is a great improvement on the speed front. Synthetic benchmarks being what they are, it looks promising: http://rubychan.de/share/yarv_speedups.html http://rubychan.de/share/yarv_speedups.html
- philwelch 16y agoRuby 1.8 uses MRI (Matz's Ruby Interpreter), which is indeed slow. Ruby 1.9 throws out the old MRI code entirely in favor of YARV (Yet Another Ruby VM), aka KRI (Koichi's Ruby Interpreter), which is considerably faster.
- nijikunai 16y agoHow well does JRuby stack up against them?
- quellhorst 16y agoI have been coding a new app with 1.9.2-head and the latest Rails 3 beta. RVM makes switching from 1.8.6 to 1.9.x easy. Haven't had any crashes and it even feels faster.
