I don't think performance is a particular criterion for the design of this language. It's not unimportant, but the quality of the code it engenders, especially w.r.t. to concurrency and the difficulty of writing correct code using conventional thread-aware mechanisms, _is_ a key design goal. > Shouldn't the number of processors on the test machine make a big > difference to how fast it runs?

There is not yet (and may never be) any ability to automatically parallelize arbitrary algorithms or code. > What happens if we run this benchmark on a nice 4 core core machine? And nothing else is running? One core will be used for the thread running this code. Another will do any I/O, though in this case there is virtually none, and another will do GC. This test is a sequential algorithm. I'm not familiar with the Alioth benchmarks / shootout, but maybe there are some parallel tests in there.
