There is some multicore support - you can set the synth.cpu-cores 
setting to the number of cores you want FluidSynth to use - but whether 
it makes a difference depends on your use case.

In short, with long buffer sizes (latency) and lots of voices, using 
more than one core is probably beneficial. If you have just a few voices 
or need very low latency, the overhead of multicore is likely higher 
than what you gain from it. So experiment to see what works best for you.
