Erlang R13A Benchmark
I made a little benchmark to check out the new Erlang Release R13A and the behavior of the multiple run queues. The benchmarking program was the same I used in another benchmark you may find here. You may also find the sources at that location. As already noted there the slope from 1 CPU to 2 CPUs is due to the “bad” implementation made to challange the Erlang SMP features. The mashine was an 8 core Intel Xeon 3 GHz with a 64bit 2.6.9 Linux, Erlang kernel polling active.
