Performance

I'm looking at putting together a high-performance multi-threaded iPhone app that's doing a couple of fairly high-intensity operations concurrently. Is the performance difference between NSThread and POSIX threading enough to care about here? If so, I would assume POSIX threads would be more efficient because it bypasses the obj-c overhead. Is this correct?
