I'm trying to use heap profiling with +RTS -hc -i1 options and running my program for about 30 seconds. However, I only get around 7 samples with seemingly bogus timetags (i.e. 0.00, 3.69, 3.73, 3.10, 4.05, 4.12). What's going on?
I'm running GHC 6.4.2 on Windows (MSYS/MinGW).
IIRC the timestamps ignore time spent in GC and time spent sampling the heap, so they measure runtime of the program only. Still, it does look a little strange. Maybe you could send us the output of +RTS -S? Cheers, Simon
