Performance Regression: -4.92%
3 warnings, 1 note
⚠️ Walltime results may be unreliableSome benchmarks used the Walltime instrument outside CodSpeed Macro Runners, which can make the results inconsistent.
⚠️ 19 benchmarks are dominated by system callsSystem calls cannot be simulated consistently and are left out of the measure. The reported value understates the real cost. Switch to the Walltime instrument to measure them.
⚠️ Base and head ran on different runner typesSome benchmarks with significant performance changes were compared across different runner types, so the changes might not come from the code. Run base and head on the same runner type, or use CodSpeed Macro Runners for more stable results.
ℹ️ 40 benchmarks have no flamegraph
The flamegraph wasn't generated: the symbols of the profiling trace could not be resolved, because no information about the language frames was collected.
⚡ 1 improved benchmark
❌ 5 regressed benchmarks
✅ 2402 untouched benchmarks

Warning
Please fix the performance issues or acknowledge them on CodSpeed.
