Andrew Mashenkov commented on IGNITE-4908:
------------------------------------------
ReentrantLock is stored as entry one of system cache.
It is possible, ReentrantLock entry updates on every thread getting the lock.
If so, we should handle such cases locally in some way when possible.
> Ignite.reentrantLock looks much slower than IgniteCache.lock.
