Dear Café, I'm quite curious about overhead of the profiler... I've compiled my program with --make -threaded -rtsopts -O2 -prof options. It was started with +RTS -N5 -p Usually, the program evaluates like 6-7 hours of real time. What is the overhead of the profiling? After 8 hours of working, the program has not finished yet. I've looked over the Internet and it seems like the overhead may be 25 times slowdown and even worse. Is it true? If yes, it's not worth waiting then :-) Best regards, Dusan
