Per Manila day, cloud-scored runs only. p95 is the judged line; the median shows the typical upload. Days with few runs swing more.

By upload size

Wall time per bucket. The 1–9 page bucket is the fixed cost of a run; the rise from there is the per-page cost. A jump in the largest bucket means a stage isn't parallel.
