afaik RP stands for retainer profiling, see

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.

Another profiling question.

2012-04-17 Thread Jurriaan Hage 
Dear all,

from the RTS option -s I get :

  INIT  time0.00s  (  0.00s elapsed)
  MUT   time  329.99s  (940.55s elapsed)
  GCtime  745.91s  (751.51s elapsed)
  RPtime  765.76s  (767.76s elapsed)
  PROF  time  359.95s  (362.12s elapsed)
  EXIT  time0.00s  (  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
