### Parameters:
|
|
|
|
<Parameter name="limit" type={"usize"} optional={true}>
|
|
|
|
number of samples to return (maximum 720)
|
|

|
### Result:
|
|
|
|
An array of `RpcPerfSample<object>` with the following fields:
|
|
|
|
- `slot: <u64>` - Slot in which sample was taken at
|
|
- `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
|
|
- `numNonVoteTransaction: <u64>` - Number of non-vote transactions processed during the
|
|
sample period.
|
|
|
|
:::info
|
|
`numNonVoteTransaction` is present starting with v1.15.
|
|
|
|
To get a number of voting transactions compute:<br />
|
|
`numTransactions - numNonVoteTransaction`
