With YARV 0.4 out, I ran the benchmark suite and got some interesting results. These are of course non-real-world results (those typically vary between 2-4 times faster) but I would be interested in seeing architechture differences. Overall, in my case YARV executed the same code in 59.3% of the time ruby took on it or in other words, a bit over half again faster. The few other people I spoke to showed times anywhere between 40-60%. There were some tests that YARV was actually slower in. Exception handling, Integer#times loops, threading and some recursion is still a bit behind (in these tests anyway).
