# getRecentPerformanceSamples

Returns recent performance samples, newest first, with transaction and slot counts per sample window.

## Request

{% tabs %}
{% tab title="cURL" %}

```bash
curl "https://<your-endpoint>.mainnet.rpcpool.com/<your-token>" -s -X POST \
  -H "Content-Type: application/json" \
  -d '{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "getRecentPerformanceSamples",
  "params": [
    2
  ]
}'
```

{% endtab %}

{% tab title="Kit" %}

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

const rpc_url = "https://<your-endpoint>.mainnet.rpcpool.com/<your-token>";
const rpc = createSolanaRpc(rpc_url);

let limit = 2;

let performanceSamples = await rpc.getRecentPerformanceSamples(limit).send();

console.log(performanceSamples);
```

{% endtab %}

{% tab title="web3.js" %}

```typescript
import { Connection } from "@solana/web3.js";

const connection = new Connection("https://<your-endpoint>.mainnet.rpcpool.com/<your-token>", "confirmed");

let limit = 2;

let performanceSamples = await connection.getRecentPerformanceSamples(limit);

console.log(performanceSamples);
```

{% endtab %}

{% tab title="Rust" %}

```rust
// Cargo.toml: anyhow = "1", solana-client = "~4.4", solana-commitment-config = "3",
// tokio = { version = "1", features = ["full"] }.
// Requires Rust 1.98.1 or newer (solana-client 4.4).
use anyhow::Result;
use solana_client::nonblocking::rpc_client::RpcClient;
use solana_commitment_config::CommitmentConfig;

#[tokio::main]
async fn main() -> Result<()> {
    let client = RpcClient::new_with_commitment(
        String::from("https://<your-endpoint>.mainnet.rpcpool.com/<your-token>"),
        CommitmentConfig::confirmed(),
    );

    let limit = 2;
    let performance_samples = client.get_recent_performance_samples(limit.into()).await?;

    println!("{:#?}", performance_samples);

    Ok(())
}
```

{% endtab %}
{% endtabs %}

## Parameters

**`number of samples`** · usize · default `720`

Number of samples to return (maximum 720)

## Response

```json
{
  "jsonrpc": "2.0",
  "result": [
    {
      "slot": 348125,
      "numTransactions": 126,
      "numSlots": 126,
      "samplePeriodSecs": 60,
      "numNonVoteTransactions": 1
    },
    {
      "slot": 347999,
      "numTransactions": 126,
      "numSlots": 126,
      "samplePeriodSecs": 60,
      "numNonVoteTransactions": 1
    }
  ],
  "id": 1
}
```

## Result

An array of performance sample objects containing:

**`slot`** · u64

Slot at which the sample was taken.

**`numTransactions`** · u64

Number of transactions processed during the sample period

**`numSlots`** · u64

Number of slots completed during the sample period

**`samplePeriodSecs`** · u16

Number of seconds in a sample window

**`numNonVoteTransactions`** · u64 | null

Number of non-vote transactions processed during the sample period

{% hint style="info" %}
`numNonVoteTransactions` is `null` for older performance samples that do not record it. To get a number of voting transactions, compute `numTransactions - numNonVoteTransactions` when this field is present. On Alpenglow clusters, blocks contain no vote transactions, so `numTransactions` and `numNonVoteTransactions` are about equal.
{% endhint %}
