--- Comment #3 from qinzhao at gcc dot gnu.org ---
(In reply to Martin Li=C5=A1ka from comment #2)

I think both size and speed.

for the full execution of our application, the GCC's profiling data is too =
big
to out of the disk space.=20=20
at the same time, since we have to merge all the profiling data for differe=
nt
processes, the merging process take a long time due to so many profiling da=
ta
files.=20

> Have you tried compressing the gcda files?
>=20
> Anyway, I'm going to work on that this stage1.

thanks a lot. this is a high priority task for us.=
