The sources for all the Lua/LuaJIT benchmarks are at:
  http://shootout.alioth.debian.org/gp4sandbox/

Since there are only three comparable benchmarks written for
Neko, I could only test these. Results from a P4 running Linux:

Lua runs recursive, fannkuch and nbody 1.5x, 1.3x and 2.4x faster
than Neko -interp. LuaJIT -O is 3.8x, 1.9x and 5.6x faster than
Neko (JIT).

Try to implement the missing benchmarks in Neko and compare
yourself. mandelbrot, partial-sums and spectral-norm are easy. ;-)
