How would you know it's happening? How would you know it's not? How have you measured/looked?

I'm know little about this area, so I'm curious.

Several popular profiler tools (valgrind, visual studio profiler, dtrace, perfmon) can track cache miss rates.

perf-tools are my favorite. The overhead is negligible, and thus any metrics you gather are very accurate. Valgrind is rarely useful, considering the execution time disadvantage.

followed by

  perf report
or, for fancy viewing, use hotspot from KDAB.

This is on linux, btw, but it should work fine with wine.
