Comparing devices

The Compare page lets you put multiple device models side-by-side for the same phase.

Pick models

The model picker shows every distinct model that has at least one completed run. Click to toggle selection.

Pick the common phase

Anvil computes the intersection of phase names across your selected models and offers those for comparison. If two models ran different profiles with no overlapping phase, Compare reports no common phases.

Pick the metric

Currently:

• read_iops, write_iops
• read_bw_bytes, write_bw_bytes
• read_clat_mean_ns, read_clat_p99_ns

Read the chart

Two overlays:

• Bar: mean of each model's run-sample values for the selected metric in the selected phase
• Scatter: every individual run's value so you can see the spread, outliers, and sample count

Hover any bar for the mean ± stdev; hover any scatter point for the specific run and its timestamp.

Share the view

The Share view button copies the current URL. The URL carries the full view state as query parameters (models=, phase=, metric=), so anyone on the same Anvil instance who opens it lands on the exact same comparison.
