--- Comment #9 from qinzhao at gcc dot gnu.org ---
(In reply to Martin Li=C5=A1ka from comment #7)
> 1) You should not generate profile data for each process to a different
> folder, but rather merge it.

not sure how to do this? can you provide more details on this approach?

> 2) I would like to know how long does one process run and what portion is
> spent in merging (and dumping) of a profile.
will try to get this info.=
