I guess there are :)
The latest message about YARV that plans to make ruby from 50% to >300% 
faster (warning benchmarks are 80% made of..) not to mention the 
rubydium JIT.
So let's join koichi and alexander hacking on them ASAP :)


About the shootout. Most of the stuff is plan useless in ruby.
You won't implemente heapsort in ruby, cause you have sort/sort_by.
Nor you would use
http://shootout.alioth.debian.org/lang/ruby/random.ruby.html
because you have rand().
(note that this gen_random algorithm is applied in other places slowing 
down even those)

Basically remeber that ruby is 'fast enough' for most things, useless 
for others. You can't have everything I guess :)


PS
Anyway, stuff from that shootout is wildly unidiomatic, just look at
http://shootout.alioth.debian.org/lang/ruby/lists.ruby.html

I remember sending a message to them but getting no feedback. Maybe I 
should try again.
