1 Hello, I've just upgraded my -rc6 to -1.0-gcc3 and decided to make an
2 (unofficial) benchmark.
3
4 I went for galeon, I had originally intended to use mozilla, but the
5 time-results borked so I go for galeon instead.. smaller codebase, so
6 its not as great difference, but it does have both c and c++ code, so it
7 might be a decent choice.

10 gcc 2.95.3 :
11 real 3m38.592s
12 user 2m46.810s
13 sys 0m28.100s
14 CFLAGS="-march=i686 -O3 -pipe"
15 CXXFLAGS="-march=i686 -O3 -pipe"

18 gcc 3.0.4 :
19 real 5m6.465s
20 user 3m27.440s
21 sys 0m30.140s
22 CFLAGS="-march=athlon -O3 -pipe"
23 CXXFLAGS="-march=athlon -O3 -pipe"

28 if you only compare the "user" time it should be enough... as the "sys"
29 show, there's a few percentages difference between them, so this is not
30 scientific or anything.
31
32 Would be interesting to compare the results as well, since those are
33 quite likely rather different with the new levels of optimization...
