Comment #8 on issue 2223 by [email protected]: 15x slower than
spidermonkey on skinning benchmark
http://code.google.com/p/v8/issues/detail?id=2223
I took a quick look, and things are a bit strange: As before, basically all
time is spent in a single function (_main). The problem is that we do OSR
(on-stack replacement) very late, so we run almost all the time in
non-optimized code. Fractions of a second before we terminate, we finally
do OSR, deopting almost immediately, because we boldly go where no v8 has
gone before... :-P (not nice, but not the main problem)
In a nutshell: The benchmark currently measures the performance of our
non-optimized code, because we do an extremely bad OSR decision. Someone
should definitely look into this.
