- Subject: pthread_mutex_lock/unlock performance?
i'm runing cygwin (1.5.25?) under win xp sp2 and i ran a simple test
which was supposed to measure the speed of pthread_mutex_lock,
increment, pthread_mutex_unlock compared to interlocked increment and
windows critical section.
the thing is that cygwin's pthread_mutex_lock performs quite lazily - it
takes about seven times more than using native critical section.
i wonder why, of course :)
thanks for your attention,
