Robert Stupp commented on CASSANDRA-8714:
-----------------------------------------
I just wanted to benchmark allocation performance - and not accessing memory
since that would add a constant overhead to the comparison. Maybe it would also
add some "negative" value to the bigger systems (c3/c4).
But this is an artificial benchmark. To benchmark a "real scenario" I'd had to
allocate more memory, keep memory allocated, use different allocation sizes and
so on. IMO that's too heavy for a JMH.
Yea - maybe it's really the thing that JNI is more optimized.
