Subject: YARV benchmarking

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).

YARV is at http://atdot.net/yarv
