Yes, YARV's GC is faster.

Actually, the ruby1.8 version was using RubyInline to do the bottlenecks
in C (forgot to turn it off), and that's why it's allocating less. YARV
is running pure ruby codepath, so the performance is even more
impressive.

I re-ran the test with inline turned off and ruby1.8 gets 34fps, YARV
gets 60fps (76% faster!)

I'll try.

Strange..
Tried the SVN trunk HEAD:
$ svn co http://www.atdot.net/svn/yarv/trunk yarv
$ cd yarv; autoconf && ./configure --program-suffix=-yarv && make
$ ./ruby-yarv  -ve 'for d,*f in [[1,2,3]]; p d,f; end'
ruby 2.0.0 (Base: Ruby 1.9.0 2006-02-14) [i686-linux]
YARVCore 0.4.0 Rev: 470 (2006-02-22) [opts: ]
1
nil

What might be the reason ? Bad libraries on my machine?


I'll paste some things (hopefully helpful)
Are there other things I could run that would help with debugging this?
