getRecentPerformanceSamples

Returns a list of recent performance samples, taken every 60 seconds. Each sample includes the number of transactions and slots in that period. This data is invaluable for network performance monitoring, TPS (transactions per second) calculations, slot time analysis, and building dashboards that show real-time network throughput and health metrics.

Parameters

#	Type	Required	Description
1	`usize`	No	Number of samples to return (maximum 720, default 720)

Response

Returns an array of performance sample objects:

Field	Type	Description
`[].slot`	`u64`	Slot in which the sample was taken
`[].numTransactions`	`u64`	Number of transactions processed in the sample period
`[].numSlots`	`u64`	Number of slots completed in the sample period
`[].samplePeriodSecs`	`u16`	Duration of the sample window in seconds
`[].numNonVoteTransactions`	`u64`	Number of non-vote transactions in the sample period
