!type array

An array of performance sample objects containing:

##### !! slot

!type u64

Slot at which the sample was taken.

##### !! numTransactions

!type u64

Number of transactions processed during the sample period

##### !! numSlots

!type u64

Number of slots completed during the sample period

##### !! samplePeriodSecs

!type u16

Number of seconds in a sample window

##### !! numNonVoteTransactions

!type u64 | null

Number of non-vote transactions processed during the sample period

<Callout type="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.
