I would be very surprised if this were the case. boost::mutex does a 
lot more.

If you want faster mutexs, use a spinlock. e.g. 
https://github.com/ned14/boost.spinlock/blob/master/include/boost/spin
lock/spinlock.hpp#L412 which can push 100m lock/unlocks per second 
(see 
https://ci.nedprod.com/view/Boost%20Thread-Expected-Permit/job/Boost.S
pinlock%20Test%20Linux%20GCC%204.8/228/console for a full set of 
benchmarks on x64, ARMv7 are at 
https://ci.nedprod.com/view/Boost%20Thread-Expected-Permit/job/Boost.S
pinlock%20Test%20ARMv7%20GCC%204.8/58/console).
