getRecentPerformanceSamples

Returns recent 60-second performance samples in reverse slot order. Each sample includes the number of transactions and slots recorded in that time window.

Request

Send a JSON-RPC 2.0 POST request with method: "getRecentPerformanceSamples". The optional params array accepts a single integer limiting how many samples are returned.

{  "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}

The result is an array of performance sample objects, each covering a 60-second window, ordered from newest to oldest slot.

Field	Type	Description
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	Length of the sample window in seconds (always 60).
numNonVoteTransactions	u64 \| null	Number of non-vote transactions processed during the sample period. `null` for older samples that did not record this field.
