I don't know why it's happening. But even though I hear a lot on how JIT can be faster than pre-compiled apps and how hight level languages (Java) can create more efficient code than low level languages (C) ---- I still am seeing C outperforming everything else in alioth <a href="http://shootout.alioth.debian.org/" rel="nofollow">http://shootout.alioth.debian.org/</a>. Even in multi core tests C apps runs faster than Erlang. Therefore faster than C still is something we are waiting to see.
