Thus the "attempt" in the # summary line. # # [ Note: in a small nod to "the profiling code can cause NUMA problems", # this also removes the "increment the last entry in the profiling array # on any unknown hits" logic. That would account any program counter in # a module to that single counter location, and might exacerbate any # NUMA cacheline bouncing issues ] # # Link:
