The perf for the vanilla git can be seen at http://www.angstrom-distribution.org/~koen/cairo/

I'll make some .perfs with the patches later on and upload them to the same location,

'ipaq h2200' means:

HP iPAQ h2200

kernel 2.6.16
400MHz armv5te (intel pxa255)
glibc 2.5
gcc 4.1.1
binutils 2.17.50
built for the ARM EABI (like the nokia770)

Koen
