Avoid copying entire mappings during type inference - #7057
Performance Regression: -0.44%
2 warnings
⚠️ 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.
⚠️ 2 benchmarks with a significant change ran on different hardwareTheir base and head results were measured on machines with a different CPU, core count or memory, so the changes might not come from the code. Run base and head on the same runner type.
