When properly used, Objective-C programs are no more likely to be preempted than any other kind of program. Message dispatch generally has constant time and is only 2.5 times the cost of a C function call.
That just cannot be true. But if you need speed you can write a direct C style subroutine and call, and it will be swift. The dynamic binding of ObC messages often isn't needed.
