Keep GPU FSST decompression on device - #9414
Performance Regression: -14.59%
⚠️ 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.
❌ 6 regressed benchmarks
✅ 2037 untouched benchmarks
⏩ 46 skipped benchmarks1
