There is some profiling stuff in the FluidSynth code itself.  I believe
it gets enabled with the --enable-profiling option to ./configure.  I
haven't played with that much recently.  Another option is to use a more
un-obtrusive method such as oprofile or something.  I would also be
interested where FluidSynth is using the most CPU and what could be
optimized.  There was some work put into using SSE/MMX type
instructions, but it turned out to be slower!  Perhaps that could be
better optimized though.
