Dear all, from the RTS option -s I get : INIT time 0.00s ( 0.00s elapsed) MUT time 329.99s (940.55s elapsed) GC time 745.91s (751.51s elapsed) RP time 765.76s (767.76s elapsed) PROF time 359.95s (362.12s elapsed) EXIT time 0.00s ( 0.00s elapsed) I can guess what most components mean, but do not know what RP stands for. I also could not find this information in the GHC documentation that is online. Can anyone tell me? Jur

afaik RP stands for "retainer profiling", see http://www.haskell.org/ghc/docs/7.4.1/html/users_guide/prof-heap.html#retain... for more information hth, hvr --

Yes, RP is the amount of time the RTS spent doing retainer profiling. Retainer profiling is a separate pass over the heap in addition to the usual heap census, which is recorded as PROF in the stats. Cheers, Simon
