CodSpeed Performance Report

Merging this PR will degrade performance by 29.75%

_{Comparing ji/cuda-host-canonical (5ccfec5) with develop (13f120f)}

⚠️ 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.

Summary

⚡ 3 improved benchmarks
❌ 7 regressed benchmarks
✅ 1252 untouched benchmarks
⏩ 1290 skipped benchmarks¹

⚠️ Please fix the performance issues or acknowledge them on CodSpeed.
