Updated the benchmark to use JMH `blackhole` and tested it with/without the blackhole flag enabled on the Java 17.0.1 compiler and got the following results: ``` Benchmark (bpv) (size) Mode Cnt Score Error Units Packed64Benchmark.packed64VarHandleLongByte_Consecutive 47 10240 thrpt 3 12381.811 ± 6265.438 ops/s Packed64Benchmark.packed64VarHandleLongByte_Sparse 47 10240 thrpt 3 19846.767 ± 1419.612 ops/s Packed64Benchmark.packed64VarHandleLongLong_Consecutive 47 10240 thrpt 3 19840.317 ± 11542.155 ops/s Packed64Benchmark.packed64VarHandleLongLong_Sparse 47 10240 thrpt 3 21213.913 ± 592.893 ops/s Packed64Benchmark.packed64_Consecutive 47 10240 thrpt 3 22211.687 ± 2118.587 ops/s Packed64Benchmark.packed64_Sparse 47 10240 thrpt 3 22870.002 ± 418.572 ops/s Compiler blackhole: Packed64Benchmark.packed64VarHandleLongByte_Consecutive 47 10240 thrpt 3 15021.054 ± 2538.483 ops/s Packed64Benchmark.packed64VarHandleLongByte_Sparse 47 10240 thrpt 3 25409.229 ± 5009.585 ops/s Packed64Benchmark.packed64VarHandleLongLong_Consecutive 47 10240 thrpt 3 25273.456 ± 21212.884 ops/s Packed64Benchmark.packed64VarHandleLongLong_Sparse 47 10240 thrpt 3 28486.621 ± 1019.290 ops/s Packed64Benchmark.packed64_Consecutive 47 10240 thrpt 3 28826.916 ± 7247.116 ops/s Packed64Benchmark.packed64_Sparse 47 10240 thrpt 3 29529.579 ± 12940.266 ops/s ``` Also plugged Packed64VHLB into PackedInts so it gets used for bpv up to 56 (included) and ran the macro test to check performance and got the following results [dynamic.log](https://github.com/apache/lucene/files/7641422/dynamic.log) Overall it's a mixed bag - with some results better especially at the beginning of the test and then mixed results in terms of performance. -- This is an automated message from the Apache Git Service.
