Robert Stupp commented on CASSANDRA-8714:
-----------------------------------------
[~aweisberg] good catch with the JNI roundtrip. JMH result are pretty obvious:
16 ops/µs for {{Native.getByteBuffer}}, 12000 ops/µs for the {{Unsafe}}
variant. I'll revert that thing.
> row-cache: use preloaded jemalloc w/ Unsafe
> -------------------------------------------
