When tested on x86_64 Linux, parking_lot::Mutex was found to be 1.5x faster than std:sync:Mutex when uncontended, and up to 5x faster when contended from multiple threads. The numbers for RwLock vary depending on the number of reader and writer threads, but are almost always faster than the standard library RwLock, and even up to 50x faster in some cases.
