Description: A mutex profiler called mutrace that in contrast to valgrind/drd does not virtualize the CPU instruction set, making it a lot faster. In fact, the hooks mutrace relies on to profile mutex operations should only minimally influence application runtime. mutrace is not useful for finding synchronizations bugs, it is solely useful for profiling locks.
レナート PID EINS! ﻟﻴﻨﺎﺭﺕ When naively profiling multi-threaded applications the time spent waiting for mutexes is not necessarily visible in the generated output. However lock contention can have a big impact on the runtime behaviour of applications. On Linux
