--- Comment #1 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
In the case of clang, that uses heap allocations a lot more than gcc,
the speedup is almost doubled:
Firefox -O3 (clang):
glibc malloc:
2305.72s user 60.49s system 331% cpu 11:54.73 total 0% speedup
tcmalloc:
2201.04s user 78.25s system 355% cpu 10:41.27 total 10.3% speedup
jemalloc:
2231.16s user 102.52s system 342% cpu 11:21.12 total 4.7% speedup
I will close this issue, because it really should be moved to the glibc
bugzilla.
