Performance & Reliability

RPC performance and reliability — latency benchmarks, rate limits and 429 errors, WebSocket vs HTTP, and failover that survives provider outages. Current coverage runs to 2 guides, including RPC Rate Limits and WebSocket vs HTTP RPC.

Each guide here is written to stand alone, so start with the headline closest to the problem in front of you rather than reading the page top to bottom.

Every page below is compiled from vendor documentation and dated published sources, and names those sources at the foot of the article. Where a spec, a price, or a version number matters, check it against the original — the link is there for exactly that.

RPC Rate Limits:

Fix RPC 429 rate-limit errors without a bigger plan: batch calls, cache repeated reads, add retries with backoff — and the math for when paying more is worth it.

WebSocket vs HTTP RPC:

Use HTTP for request-response, WebSocket for real-time subscriptions. Learn exactly when to use each, how they fail, and the decision framework per workload.
