Hi!
If we spend so long blocked on memory reads that we're only utilising 50% of a core's time then there's lots of room for improvements if we can fill in that wasted time by running another thread.
How can you see how much does your program wait because of L2 misses? I have been playing lately with dual Quad-Core Intel Xeon Mac Pros with 12 MB L2 cache per CPU and 1.6 GHz bus speed and it would be interesting to check this things there.
