gRPC streaming latency. Transaction landing times. Full distribution — P50, P95, P99. Every test has a date, a node, a run count, and a public link.
Aperture is a shred-native gRPC feed. We ran 20,000 transactions head-to-head against Yellowstone and measured which feed saw each transaction first — and by how much.
Overall latency difference across 20,000 slots: Shredstream is only 0.1ms faster on average, 0.4ms at P95, 2.1ms at the tail. The gap is this small because Aperture runs server-side filters and reduced bandwidth — it does more work on the same latency budget.
Beam scores providers in real time and routes each transaction to the top performer. P90 is weighted 4× in the scoring — tail latency is where landing fails under load. Available on all paid plans (extra fees via partners' network).
| Provider | Avg landed | P90 landed | Performance score | Avg ack |
|---|---|---|---|---|
| beam-astralane | 330ms | 589ms | 97.42% | 53ms |
| rpcfast-rpc (standard) | 457ms | 1,065ms | 82.20% | 28ms |
Every number includes the test date, node spec, run count, and scoring formula. Runs are linked — check them yourself.
