I read your benchmarks on Ruby, but you didn't list the implementation or version of Ruby you used.

I'd guess you used MRI 1.8.X.

I decided to benchmark other versions(and implementations) of Ruby.

= jruby 1.6.4 (7.3 seconds)

      user     system      total        real
  7.388000   0.000000   7.388000 (  7.349000)

= Rubinius 1.2.4 (Little under 6 seconds)

   user     system      total        real
  5.940015   0.006878   5.946893 (  5.842485)

= CRuby 1.9.2 (38 seconds)

      user     system      total        real
 38.250000   0.090000  38.340000 ( 38.376857)

= CRuby 1.8.7 (Little under 137 seconds)

      user     system      total        real
  136.960000   0.240000 137.200000 (137.437748)

Thanks!

Exactly -- for a fair comparision, V8 (which has a JIT) should be compared against Rubinius (for Ruby) and PyPy (for Python), which will both be nearly as fast as V8.

Of course, it is true that V8 is ubiquitous, whereas Rubinius and PyPy are not -- that is the one majore advantage of javascript.
