Memory cache optimizations

Yes you can use perf to profile on cache misses (perf record -e cache-misses).

Not only that but you can annotate the source and see which function and which instruction (C or asm) caused it. This way you know exactly which field is the one causing cache misses.
Dito for branch miss-prediction.
