Ok I have added -mfpmath=sse to the 32-bit CFLAGS and the readback
performance increased from 30.44 Mpixels/sec to 48.92 Mpixel/sec. We
are getting closer to the 64-bit performance.
hmm. you should try -msse2 too. It's implied on 64bits, and I'm not sure if

Hi Michel,
thanks for the reply and your suggestions.
It took me a while to figure out how to use and run oprofile but finally I was
able to produce some hopefully useable output.

clearly stands out when comparing the 32 bit and 64 bit profile.
I'm afraid that's a red herring, as I
