Ethereum RPC latency benchmark
Warm localhost performance and cold upstream performance are different products. This benchmark measures them separately and validates every Ethereum response.

Sustained RPS in the published concurrency-32 audit
What was measured
| Test | Workload | Published result |
|---|---|---|
| Warm proof | 300 repeated eth_getBalance reads at an explicit finalized block | 300/300 valid; 1.55ms p50, 2.84ms p95, 3.32ms p99 |
| Sustained load | 2,000 validated calls, concurrency 32 | 10,076 RPS on the measured Mac |
| Privacy | Foreground edge messages during 300 warm reads | Zero |
| Correctness | Canonical safe head and JSON-RPC validation | Gate passed; zero RPC errors in proof window |
Scope: These figures do not mean an uncached Internet request completes in 1.55ms. A first-ever or expired read still pays local processing, network, Worker, and upstream-node latency.
Run the shipped harness
curl -fsSL https://rpc-relay.pages.dev/install.sh | sh rpc-relay-pro setup rpc-relay-pro benchmark rpc-relay-pro audit
Distribution verified July 22, 2026: the exact downloadable v1.2.0 archive was extracted outside the repository and its included
rpc-relay-pro audit command passed. That run returned 300/300 valid warm reads, 2.33ms warm p95, 11,099 sustained warm-cache RPS, and zero added RPC errors. The running accelerator held a non-null multi-upstream canonical safe head; a subsequent two-validation observation window added zero failures.How validity is checked
The harness rejects HTTP failures, JSON-RPC errors, malformed Ethereum results, missing local-cache headers, warm traffic leakage, and a missing canonical safe head. It reports client wall time separately from accelerator compute time.
Benchmark questions
Why can a cold call take tens or hundreds of milliseconds?
It must reach an upstream Ethereum node. Local caching removes that trip only after a safe result is available.
Does 10,076 RPS mean the Pro edge quota is 10,076 RPS?
No. It is localhost warm-cache capacity in one measured load test. The published Pro service limit is 300 calls per 10 seconds.
