[infinispan-dev] write-heavy performance degradation between 5.1 and 5.2

[Radim Vansa]

Hi, I've checked it on 4 nodes, stress test 15 minutes with 80% writes. Both reads and writes have improved in 5.2

READS/sec 247k -> 263k
WRITES/sec 4547 -> 4771 (note: this is average, coordinator has about 2x more writes as it is the lock owner for all locks in replicated mode)
that makes

Paul, how many operations within transaction do you use? The results above are from single operation (put/get) per transaction (we have improvement in TRANSACTIONS/sec 5655 -> 5936 with this setting), I'll try to rerun with more ops/transaction as well.
