------- Additional comments from [EMAIL PROTECTED] Fri Oct 6 06:43:15 -0700 2006 ------- The sal functions osl[in|de]crementInterlockedCount() use atomic operations to increment and decrement a counter. On all x86 platforms this is done with a "lock xadd" prefix. "Lock" means here to lock the bus, a quite expensive operation on pre HyperThreading Intel processors and quite uncessary if there is only one non HT, single core processor in the system (xadd with prefix is around 8 times slower than without prefix). The new implementation checks if we are on a single processor single core non HT machine and leaves the "lock" prefix out in this case. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
