Ruby gets chrome plated with V8
rbv8, and ran some benchmarks.
In one simple benchmark,
rbv8 took 0.987 seconds. The same benchmark took 9.565 seconds in Ruby 1.8.6, making rbv8 ten times faster. A C version of the benchmark executed in 3.322 seconds, but comments indicate the C code was somewhat unoptimised. Cournoyer advises caution with these benchmark numbers; other benchmarks he ran had
rbv8 running slower, often much slower.
For a simple hack though, done in less than 24 hours after V8 was released, it opens up the possibility that V8 could potentially be a key to better Ruby performance.
