URL: https://github.com/apache/lucene/pull/177#issuecomment-861222097
Here is the results of the original pull request without the unsafe memory
copy, using the `fromArray()` and slicing code. During runtime, the benchmark
runs 72 seconds vs 60 seconds. The 12 seconds are mostly caused by garbage
collection and allocations.
At the end of the report you see an overview of the heap allocations seen by
JFR:
