I ran a benchmark on a library i'm working on (fuzzy auto complete), and rubinius was the fastest (I didn't test 1.9). The code is pure ruby, it creates a decent sized trie then walks it once to set data in each node (a sequential forward index, etc). I'll release the code once my library is ready for public consumption, but the numbers were (in seconds): rubinius ~ 4.85 jruby 1.5 ~ 5.45 mri 1.8.7 ~ 9.35 ree 1.8.7 ~ 9.35 and Yes, I did a warm up.
