What kind of performance hit will linux take using MMX?

>From what I understand, everytime you switch between MMX mode and regular
FP mode, 100 or so cycles are burned. If you are context switching
alot (any multitasking enviornment), this would seem to add up. Or is
it insignifcant to the amount time required for a context switch?
