The upload metadata now reports the isolation level of the machine running the benchmarks, as runner.isolation.

The machine running the job sets it in CODSPEED_RUNNER_ISOLATION; CodSpeed Macro Runners set it to strict, for example. The runner trims the value and leaves the field out when the variable is unset or blank, so uploads from other environments are unchanged.

The backend support is not released yet. Until it is, the field is ignored like any other unknown metadata.

⚠️ Walltime results may be unreliable

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

⚠️ 8 benchmarks are dominated by system calls

System 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.
