perf timechart
the first command will do a 10 second recording of the activity in your system
the second command will turn the recording into a svg image.
with that, it's maybe possible to figure out what is going on, assuming the actual stuttering can be captured (if it's very reproducable, it should be)

BFS did show that the scheduler in 2.6.30 and early had issues, great, but 2.6.33 has a vastly improved scheduler... not so sure where BFS is better.. I haven't seen any kind of somewhat objective results.

the png is not very detailed (yay zoomable svg) but it is really looking like you have the VM system working hard, and various things then turn IO bound.
It really does smell like a VM issue, but again, that's from a low res view..
