I can guess what most components mean, but do not know what RP stands
for.
afaik RP stands for "retainer profiling", see
http://www.haskell.org/ghc/docs/7.4.1/html/users_guide/prof-heap.html#retainer-prof
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.
