Hi, what is the expected runtime degradation by using callgrind with cache simulation? Currently I see that starting callgrind with --instr-atstart=no causes a degradation by a factor of 10 (32 hours instead of 3). Using the real instrumentation seems to cause another factor of 8. Altogether I see a slowdown factor of 80 in the part of the programm I want to profile. Are the values reasonable or is there something wrong here? Christoph |
