Try halving the sample rate with the flag '-r22050' (this halves the CPU workload for some part of fluidsynth code)
See: http://sourceforge.net/apps/trac/fluidsynth/wiki/ExampleCommandLines fluidsynth on NetBooks and low performance computers
The only way I have found to sort out performance problems is to add special debug code that measures how long it takes to execute all the time critical functions/methods in mSec.
Equally well someone at Ubuntu or elsewhere could have fiddled with some time optimised code that now eats up much CPU.
