CodSpeed WallTime Performance Report

Merging #1811 will degrade performances by 63.77%

_{Comparing ci/codspeed-fix-instance (9b86249) with feat/new-execution (6dffa9b)}

⚠️ 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.

#### 🎉 Hooray! `codspeed-rust` just leveled up to 3.0.2!

A heads-up, this is a breaking change and it might affect your current performance baseline a bit. But here's the exciting part - it's packed with new, cool features and promises improved result stability 🥳!

Acknowledging the performance degradation because: codspeed updated to v3.0.2 and changed to a fixed m5a.xlarge instance type (intentionally only 2.5Ghz instead of the faster 3.5 Ghz available on m6a.xlarge).
