By the way, it looks like Windows 8 supports something akin to futexes. At least the two basic operations are present: http://msdn.microsoft.com/en-us/library/windows/desktop/hh706898(v=vs.85).aspx WaitOnAddress http://msdn.microsoft.com/en-us/library/windows/desktop/hh706900(v=vs.85).aspx WakeByAddressSingle That means on Windows 8, we should get efficiency similar to Linux on all cases. PS: Windows 8 is still missing some of the more advanced operations like compare-and-requeue, which are necessary to avoid the "thundering herd" problem. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center Intel Sweden AB - Registration Number: 556189-6027 Knarrarnäsgatan 15, 164 40 Kista, Stockholm, Sweden
