PolyNode case studies test a concrete product claim against a defined denominator. Each study records its date, endpoints, subscription semantics, source versions, measurement clock, eligibility window, adverse observations, and limitations.

PolyNode vs Struct and RTDS

WebSocket latency and confirmed-fill completeness measured on August 1, 2026.

Evidence standard

Every benchmark case study should:
  • define equivalent signals before measuring them;
  • timestamp all competitors from the same monotonic clock and process;
  • use an independent completeness denominator when one exists;
  • exclude partially observed boundary intervals;
  • preserve per-sample data, missing identifiers, source hashes, and connection lifecycle events;
  • report unfavorable windows and unavailable comparisons;
  • separate measured results from broader product claims;
  • publish code with credentials supplied only at runtime.
These are point-in-time measurements, not guarantees about every network location or future provider version.
