Slang compile-time performance — per benchmark
21 releases + 2 daily ToT runs, 25.14 → 06-26 · metric: median (ms) · 25 workloads. The 2 rightmost points per panel are daily top-of-tree builds.
Phase composition across releases — main phases
One panel per workload; the two top-level phases frontEndExecute (green) and generateOutput (orange) stacked as areas across the release history, top edge tracing compileInner (own zero-based y-axis per panel; × = first→last ratio). Click a workload name to open its own page with the full sub-counter breakdown (specializeModule, simplifyIR, SemanticChecking, …).
