For now i can't reach this tps with 56core x 3 server = =3D 168 core. All get operations are made from servers. Seems like locking the keys causes the problem. Cus i see lots of threads waiting for a lock on get operation. There are ~100 entries in the cache. This is our configuration. Can you see any improvements on configuration.

What cache provider did you use before?
