Speed Test

Measured frame time. Lower is faster.

Median time per frame · release build
80 × 2460 µs
200 × 60249 µs

Each result is the median of five runs of 240 frames. Timing covers widget paint, diffing, ANSI encoding, and a counting sink write; terminal rendering and model updates are outside the measurement. Method and full results
