While doing profiling, I saw that this function was incredibly slow compared to the blazing performance of everything else, so switched to single producer / consumer everywhere. Now the user thread of RakNet is not threadsafe, but it's 100X faster than before. class RAK_DLL_EXPORT SimpleMutex : public RakNet::RakMemoryOverride { public: /// Constructor SimpleMutex(); // Destructor ~SimpleMutex(); // Locks the mutex.
