Hello,

If you have noticed my Scalable and distributed Lock uses now
a Ticket mechanism, but my Scalable distributed Lock is more
efficient than the Ticket Spinlock cause it's distributed and
hence the threads spins on local variables so it reduced the cache
misses and the cache-cohence traffic, so my scalable distributed Lock
is more efficient than the Ticket Spinlock.



Thannk you,
Amine Moulay Ramdane
