We are observing that on a Quad G5 we get glitches or dropouts when we
lower the buffer size under high audio load (of course); but with all
four cores enabled, we get these glitches far earlier (with a higher
buffer size) than with only one core enabled.
1) Why is this?
2) Is there anything we can do about this? (Short of telling our users
to turn off three of their four cores.)
We were thinking if it were possible to "pin" the HAL IO thread to a
particular processor/core, maybe that would help. Is this possible?
