JMH summary — classic (commit 4e1bee3)

Speedup vs trailing 90-day baseline on gh-pages. Higher = faster.
1.00 = in line with history. Per-benchmark ratio, geomean within group.
Time-per-op units inverted so direction is consistent. The calibrated
column divides out this runner's speed vs the baseline hardware, as
measured by Groovy-independent pure-Java ruler benchmarks.
