📁 popular-libs

📊 Size Changes

No significant regressions detected 🎉. Total bundle size decreased slightly from 1,806,629 bytes to 1,806,603 bytes (-26 bytes). Initial JS chunk also reduced (1,806,340 → 1,806,314 bytes).

🔍 Root Cause Analysis

• mobx: Parsed size reduced marginally (57,681 → 57,655 bytes), likely due to minor build environment variance or tree-shaking improvements.
• No new modules or duplicate dependencies detected.

⚠️ Risk Assessment

Overall severity: Low

• Initial chunk size decreased; there is zero negative impact on load performance or time-to-interactive.

💡 Optimization Suggestions

1. Maintain Configuration: Current tree-shaking settings are effective; no immediate changes required.
2. Monitor MobX: Ensure only necessary APIs are imported to keep the mobx footprint stable in future updates.

📁 ui-components

📊 Size Changes

No significant regressions detected 🎉. Total JS size decreased slightly (4,964,432 → 4,964,404 bytes).

🔍 Root Cause Analysis

• Minor parsed size reduction in @ant-design/colors (v6 & v8) drove the negligible total decrease.
• No new modules added; existing dependencies remained stable.

⚠️ Risk Assessment

Overall severity: Low

• Total bundle size decreased by 28 bytes with no impact on initial chunk load time.

💡 Optimization Suggestions

1. Deduplicate Dependencies: Both @ant-design/colors@6.0.0 and @8.0.1 are present in the bundle. Align versions to eliminate duplication.
2. Audit Dependency Tree: Investigate why two major versions of the colors package are required simultaneously.

Pull request overview

This PR updates the Rust benchmarking GitHub Actions workflow to pin the walltime benchmark execution to a specific CPU set, aiming to reduce scheduling noise and improve measurement stability.

Changes:

• Wrap walltime benchmark commands with taskset -c 300-315 to bind execution to dedicated CPUs.
• Apply CPU pinning to both cargo codspeed run ... and pnpm run bench:rust paths in the walltime step.

⚠️ 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.

⚠️ Different runtime environments detected

Some benchmarks with significant performance changes were compared across different runtime environments,
which may affect the accuracy of the results.
