Release Notes

CodSpeedHQ/codspeed-rust (divan)

v6.0.0

Compare Source

CodSpeed for Rust 6.0.0 removes a source of measurement noise from your CPU Simulation benchmarks, so you can spend less time investigating unexpected changes in unrelated results.

Highlights

Your Divan and Criterion benchmarks now run in separate processes. Changes to one benchmark no longer carry allocator state into the benchmarks that follow it, improving consistency as your benchmark suite evolves.

Early results showed lower run-to-run variance, with roughly 70% fewer benchmarks varying by more than 1%.
No benchmark code changes required. Your WallTime results are unaffected.

Breaking Changes

• Some benchmark values may shift when you upgrade
• Each benchmark adds small process startup overhead to the run

Set CODSPEED_PROCESS_ISOLATION=false to revert to the previous behavior.

What's Changed

• fix(criterion): avoid duplicate setup in simulation iter_batched by @​not-matthias in #​198
• feat(divan): run each benchmark in its own process by @​not-matthias in #​194
• feat(codspeed): declare a Symposium plugin by @​adriencaccia in #​200

Full Changelog: CodSpeedHQ/codspeed-rust@v5.0.3...v6.0.0

⚠️ Base and head ran on different runner types

Some benchmarks with significant performance changes were compared across different runner types, so the changes might not come from the code. Run base and head on the same runner type, or use CodSpeed Macro Runners for more stable results.
