How To Read This
reflex has the strongest relative profile in this run, 7.7% ahead of alien-signals by geometric mean. It also takes 28 of 45 scenario wins, while alien-signals takes 13.
This page intentionally treats benchmarks as workload families rather than a single universal speed claim. Median is the primary row score; p95/p99 and CV show predictability.
Interpret wins through the scenario taxonomy: creation, update, pull/push propagation, dynamic dependency churn, large graphs, lifecycle pressure, and memory behavior can favor different runtimes.
