--- Comment #17 from Artem S. Tashkinov <t.artem at mailcity dot com> 2011-01-31 21:46:29 UTC ---
At least on i686 platform the difference is marginal (GCC flags: -O2
-march=pentium-m -fomit-frame-pointer, Intel Core Gen 2 CPU):

GCC 3.4.6
real    0m15.859s
user    0m15.662s
sys     0m0.177s

GCC 4.5.2
real    0m16.147s
user    0m15.939s
sys     0m0.187s

I'm compressing a 400MB TAR archive containing miscellaneous binaries and
documentation. So the issue is m68060 specific.

--- Comment #21 from Jeffrey A. Law <law at redhat dot com> ---
Without an in-depth analysis from someone with real hardware there's simply
nothing we're going to be able to do here. 

Sadly we don't have good tools in the m68k world like valgrind, oprofile, etc
which would allow for a good in-depth analysis of what's going on.  And I've
found performance testing within the anarym emulator to be too variable to be
of any value.

I'm closing as WONTFIX as that's the sad, unfortunate reality.
