I was hesitating if I should even mention these, but I had the same
reaction to these numbers (1.2.6 vs 1.3.4 on the Monahans board we
have at work, no FPU):

image-rgba             tessellate-256-100  11428.91 0.01% ->  10.25
1.66%: 1114.58x speedup

image-rgba        zrusin_another_fill-415  1483.33 0.02% ->  59.28

0.44%: 24.20x speedup

Now, yes, they look totally bogus. However, I have gotten these
numbers three times now so I am inclined to actually believe their
validity. What is clear as day though is that these are not simply
1.3.4 "being better", they are 1.2.6 doing something horribly wrong.
So the inverse of that could be that 1.3.4 is doing something right,
which is very nice ;)

The actual logs are available,  in case anyone wants to ogle them:

http://kalle.vahlman.googlepages.com/cairo-perf-run-1.3.4-2006-11-30.log

I wouldn't take these numbers too seriously without knowing more about
where it all happens, but thought thry would amuse people (they surely
amused me :).
