| Collected 4 samples per benchmark/VM, with 4 VM invocations per benchmark. Ran 10 benchmark | |
| iterations, and measured the total time of those iterations, for each sample. Emitted a call to | |
| gc() between sample measurements. Used 50 benchmark iterations per VM invocation for warm-up. Used | |
| the jsc-specific preciseTime() function to get microsecond-level timing. Reporting benchmark | |
| execution times with 95% confidence intervals in milliseconds. |
