lower throughput/higher latency of KV after switching to openSSL 1.1.1 (Java client)

After adding support of TLS 1.3 and switching to openSSL 1.1.1 we got better pillowfight throughput (max throughput increased from 320K to  663K)

But Java SDK based test (YCSB) got slower. 224K to 177K.

Tested with java SDK 2.7.0.

Will test also with Java SDK 3 if support is there and update the ticket

Build: 6.5.0-2856
