Solana RPC latency benchmarks, June 2026: what the public endpoint actually costs you

We ran 12-sample latency benchmarks across Solana's public RPC endpoint and two major free-tier providers, testing six methods. getSignaturesForAddress on the public endpoint averages 1,201ms. On a free third-party node: 265ms. On Superbank (RPC 2.0): 50ms.
