> This is a dated observation from one development host. It is not a universal provider ranking or an FRB product benchmark.

## HTTP observations

| Provider | Successful / attempts | Median (ms) | p95 (ms) | Maximum observed head lag (blocks) |
| --- | ---: | ---: | ---: | ---: |
| dRPC public | 5 / 5 | 104.5 | 150.31 | 0 |
| PublicNode | 5 / 5 | 94.16 | 136.19 | 0 |
| 1RPC public | 4 / 5 | 216.45 | 895.78 | 1 |

## WebSocket observations

| Provider | Open (ms) | Subscribe ack from start (ms) | Events received / requested | Terminal error |
| --- | ---: | ---: | ---: | --- |
| dRPC public | 129.04 | 202.8 | 2 / 2 |  |
| PublicNode | 129.11 | 203.27 | 2 / 2 |  |

## Interpretation boundary

- The development host network egress region was not independently verified.
- The sample is intentionally small and rate-limited; it cannot establish a durable trend.
- HTTP connection reuse and provider-side routing are implementation-dependent.
- A returned block number or subscription event does not prove transaction acceptance, inclusion, finality, protection, or economic performance.
- Provider behavior, routing, chain conditions, and public endpoint policies can change after this observation window.
