It would help if you could profile your use of GEGL. Given the knowledge of where the processor spends most of its time, it should be easier to find out if there are options you could tweak to improve this. Or do you have the impression that the speed is I/O bound? In other words, does GEGL use all of the CPU cycles available or is it trashing your disk? You might find sysprof useful as a tool for profiling GEGL: http://www.daimi.au.dk/~sandmann/sysprof/ It doesn't require you to recompile the code you want to profile and there's chance that your distro has sysprof packaged already.
