From b02e597450f28c7374afdafd97b15a889a8107da Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Mon, 22 Jun 2026 18:27:57 -0700 Subject: [PATCH] perf tests: Speed up metrics checking shell tests Optimize the execution of the metric validation and metric listing shell test suites: 1. `stat_metrics_values.sh`: The Python metric validator runs the `perf bench futex hash` workload for each validated metric relationship. Reduce the benchmark runtime limit from `-r 2` (2 seconds) to `-r 1` (1 second). This cuts the workload duration in half while still generating sufficient PMU events to satisfy non-zero threshold metric validations. 2. `stat_all_metrics.sh`: The metric checking test runs `perf stat` sequentially across all 433+ listed metrics. Change the default workload for system-wide runs from `sleep 0.01` to `true`. This avoids the 10ms sleep delay on each sequential metric invocation, saving over 4 seconds of total wall time during full test suite runs.
