I also ran the same with tiered compilation turned on and no `-Xbatch` (java
defaults). The results are much better, but still the heap allocations are done.
For long-running benchmarks with modern VMs, switching off tiered and
enabling batch mode is a bad idea, as it is different from real world. Sure,
results are more predictable, but they are noisy anyways (for different
reasons, mainly because we don't use JMH). In addition, as soon as you use
MethodHandles or VarHandles (as we do here), in addition to Hotspot's low level
optimizations, the Java runtime also does lambda transformations of the
MethodHandles and VarHarndles at runtime (it rewrites byte code), which cannot
be controlled by the Java command line. All code using java Lambdas, dynamic
invokes, MethodHandles, VarHandles (like this one) only work well after long
runtime. So the benchmarking will stay noisy unless we use JMH. This got worse
recently as Lucene code uses more and more Lambdas.
