You can give the compiler options with something like: CFLAGS="-O3 -ffast-math -funroll-loops" ./configure ... You could try looking at the FP options, Pango (and maybe Cairo?) used to use a lot of floating point which caused performance problems on machines without FP support. Though I think this is supposed to have got a lot better recently. You could try gtk 2.8 (or was it 2.6? I forget), this was the last version before rendering switched to Cairo/Pango, so it should be easier on your hardware. You could check which theme you are using, obviously some are much 'heavier' than others. The built-in default theme is relatively light, I think.
