Method

How a number on this page got measured

Same machine, same dataset, same compiler flags. Variance comes from your code.

  1. 01Your submission is replayed against a held-out 10.04 M tick dataset. Memory is capped at 512 MB and wall clock at 60 s.
  2. 02Every call to on_tick(...) is individually timed.
  3. 035 replays. Median of the resulting p50 / p99 / p999 wins. Throughput is total ticks divided by total wall time.
