Some benchmarks used the Walltime instrument outside CodSpeed Macro Runners, which can make the results inconsistent.

Some 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.

The flamegraph wasn't generated: the symbols of the profiling trace could not be resolved, because no information about the language frames was collected.
