Hello,
it's been a while since my last comparison of various GCC's compilation
performance on MICO sources. A lot happened in GCC development since
then and so I'm here with more up-to-date measurements. This time I've
used MICO 2.3.12 release sources and again measured time of
compilation of orb subdirectory files. I've compared my GCC 4.0.1
release with GCC 4.1.0 20060210 prerelease on AMD64 generating code
for this platform. Whole tables are below, but overall results are,
that 4.1.0 is slower on all compilations (sums) while using
-O0/1/2/3/s optimization levels, actual numbers are:
-O0: -4%
-O1: -21%
-O2: -19%
-O3: -19%
-Os: -9%
since I don't know current GCC policy for considering compilation
performance regressions, I'm not able to judge what's regression and
not. Anyway, interested developers might look into the tables below
and if they need more details ask me to provide more information.
Cheers,
Karel
PS: time is measured in seconds, numbers are provided by -time GCC
option.
