Well... not always, these days. On multi-socket systems, if the system architecture guarantees that timestamps are monotonically increasing regardless of which CPU checks the time, there may actually be significant bus traffic to insure that kind of result every time the clock is read. There's a future Intel chip architecture which should eliminate the problem (don't remember the time frame), and it's not an issue on single socket boxes (and not much of one on dual sockets). - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
