Setup

Results in local laptop using JDK 17. Running on a 2018 MacBook Pro, 6 core Intel i7 2.2ghz, 32GB RAM, MacOS 12.6.2.

In the OffHeapGetPutBenchmark test NMA and RocksDB are populated with 50,000 byte array values of size 100KB each (5GB of data)

The keys are the strings "0" - "49999"

In NMA tests data is not persisted on disk.
