It is. I asked the question because I had talked about the performance of recursive mode in my email that Philipp replied to. I was a bit confused about the question. Now, while the difference in performance was quite surprising, I must point out that it's still plenty fast. It just happens that CRITICAL_SECTIONS are faster. I should also point out that QMutex is optimised for uncontended situations, which is the most common case for GUI applications shuffling some data to worker threads. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
