Are counting to 1000000000 and compiling gnumach both very cache intensive applications? I can't see how the 1000000 example is, and GCC is mostly sensitive to the cache size, not bandwidth-bound. Try something where the working set is greater than the cache size and you might see some results. Kenneth Østby
