Trying to use prefetch without a profiler is a waste of time. 2: whenever you find an instruction in a critical place that is anomalously slow, you have a candidate for a prefetch. Often the actual problem is on the memory access on the line before the slow one, rather than the slow one as indicated by the profiler.
