When WOULD it make a difference? The only thing I can think of is you don't have to make a call to a subroutine. But all that saves you is dealing with the stack. My tests are mostly generating stimulus for the dut. The "OK" function is probably 0.001% of my processor time. Even if I use a macro and make my "OK" function run ten times faster, its only 0.0001% of my processor time.
