getRecentPerformanceSamples — Solana RPC Method

getRecentPerformanceSamples returns performance metrics sampled every 60 seconds, including the number of slots, transactions, and non-vote transactions processed in each window. This is the standard way to calculate Solana’s transactions per second (TPS).

Parameters

Request

curl -X POST https://api.mainnet-beta.solana.com \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "getRecentPerformanceSamples",
    "params": [5]
  }'

TypeScript (@solana/kit)

import { createSolanaRpc } from "@solana/kit";

const rpc = createSolanaRpc("https://api.mainnet-beta.solana.com");
const samples = await rpc.getRecentPerformanceSamples(5).send();

for (const sample of samples) {
  const tps = Number(sample.numTransactions) / Number(sample.samplePeriodSecs);
  console.log(`Slot ${sample.slot}: ${tps.toFixed(0)} TPS`);
}

Response

{
  "jsonrpc": "2.0",
  "result": [
    {
      "slot": 341200000,
      "numSlots": 150,
      "numTransactions": 450000,
      "numNonVoteTransactions": 180000,
      "samplePeriodSecs": 60
    }
  ],
  "id": 1
}

Samples are ordered from most recent to oldest.

Calculating TPS

• Total TPS: numTransactions / samplePeriodSecs
• Real TPS (excluding votes): numNonVoteTransactions / samplePeriodSecs

Vote transactions typically account for 50-80% of total transactions on mainnet. The “real TPS” metric (non-vote) is a better indicator of user activity.

Common errors

• Invalid limit — values above 720 return an error.

Performance

The response contains up to 720 small objects (12 hours of 60-second samples). Even at maximum limit, the response is compact. Safe to call periodically for dashboard updates.

FAQ

How do I calculate current TPS? Take the most recent sample and divide numTransactions by samplePeriodSecs. For non-vote TPS, use numNonVoteTransactions instead.

Why is TPS so much lower when excluding vote transactions? Validators submit vote transactions every slot to participate in consensus. On a network with 1,500+ validators, this generates thousands of vote transactions per second. Non-vote TPS reflects actual user and application activity.

How far back do samples go? Up to 720 samples at 60 seconds each, covering approximately 12 hours of data.

What is a typical TPS for Solana mainnet? Total TPS (including votes) is typically 2,000-5,000+. Non-vote TPS varies widely with demand, ranging from 500 to 3,000+ during peak periods.

How many slots should I see per sample? At 400ms per slot and a 60-second window, expect approximately 150 slots per sample. Fewer indicates a higher skip rate.
