Hi all, I'm sure the SMP features along with removal of the Big Giant Lock (TM) are designed to sacrifice as little performance as possible across the board. In practical terms, will a 5.0 kernel without SMP have any performance loss at all on a single CPU machine compared with the 4.x kernel we use now? I once read here on one of these lists that the Solaris fine-grained locking was great for SMP, but was a lot of overhead for single CPU machines (correct me if I misunderstood). If there's a discussion you can point me to that will save the trouble of explaining it (again) let me know. NOTE: Please CC me, as I am not currently subscribed.
