* Fix performance regression on Mac OS X when creating/destroying QMutexBradley T. Hughes2011-10-211-44/+6
| | | | | | | | | | | | This reverts commit cf17b743d2fe84ab259b7232ab07b58a1872e18e, which changed QMutex to use a Mach semaphore_t on Mac OS X. We now use pthread_mutex_t on Mac OS X as well. Contention performance is mostly unchanged, but the new constructionQMutex() benchmark added in this commit shows that creating/destroying a semaphore_t is about 20 times slower than pthread_mutex_t.

* Do not allow multiple threads to acquire a QMutexBradley T. Hughes2011-05-051-5/+8
| | | | | | | | | | | | | | After the mutex optimizations on Mac, we did not handle the case where semaphore_wait() could return KERN_ABORTED. Under heavy contention, this happens, and when running in release mode, the assert in qmutex.cpp is not executed. The code silently allows multiple threads to continue as if it had acquired the mutex exclusively. Fix this by checking for KERN_ABORTED from semaphore_wait(), and retry the wait. We do not handle KERN_ABORTED for timed waits, simply return false and let the code doing the tryLock() handle it how it deems best. Reviewed-by: joao

* | Track average wait times under our maximum spin time thresholdBradley T. Hughes2010-12-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Further observation shows that spin times slightly over the average wait time produce the best results. This change keeps a heavily weighted average of the wait times under 1.5ms (1.5 times the max spin threshold), and adjusts the spin time to be 150% of the average wait time. Introduce spin time adjustments when spin locking works, and adjust to between 150% of the average wait time and the maximum threshold. Reviewed-by: joao
* | Optimize adaptive spinning mutex codeBradley T. Hughes2010-12-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the adaptive spinning code to be elapsed time based instead of iteration based. The new approach will quickly reduce the amount of allowed spinning time when it detects that lock contention is resolved by waiting instead of spinning. We get better results by dynamically adjusting for elapsed running time instead of trying to fine tune iteration counts that won't work for all CPU types, speeds, etc. From observation, lock performance suffers if the spin time is higher than the minimum wait time. Because of this, QMutex never increases the spin time, it only reduces the spin time to the minimum observed wait time. For very long wait times, we disable spinning completely (and always resolve contention by waiting). Use QThread::yieldCurrentThread() when spinning on a contended mutex. Comment from the code: be a good citizen... yielding lets something else run if there is something to run, but may also relieve memory pressure if not. Reviewed-by: joao
* | Improve QMutex contention performance on LinuxBradley T. Hughes2010-12-201-5/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use futex(2) to implement QMutexPrivate::wait() and ::wakeup(). This makes QMutex perform more or less identically the same as pthread_mutex_t when contended. We have to use the contender count in a different way due to the way that futex() waiting works. Waiting on a futex atomically checks that the value has not changed from the expected value and then puts the thread to sleep. So, on Linux, the contender QAtomicInt will only ever be one of three values: 0 for unlocked, 1 for locked, 2 for contended. This does mean that there is a slight chance for unfairness due to the fetch-and-store to zero in the wakeUp() function, but unfortunately this cannot be avoid as the code is now. Reviewed-by: joao
