Correctly restore unstable encoding corpus and create tokio runtime only once per process#8480
Performance Regression: -22.94%
⚠️ Unknown Walltime execution environment detected
Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data.
For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.
⚡ 4 improved benchmarks
