get
Returns recent per-sample-period throughput statistics for the cluster.
getRecentPerformanceSamples returns historical samples, each covering roughly 60 seconds, with the slots and transactions processed in that window. TPS is numTransactions / samplePeriodSecs.
Samples are newest-first and pre-aggregated by the node, cheaper than deriving throughput from individual blocks.
Parameters
params is a JSON array, with values in this order: limit.
Number of samples to return, newest first. Defaults to the node's maximum retained sample count.
1Maximum: 720Result
Performance samples, newest first.

Last slot included in this sample.
Total transactions processed during the sample period (includes vote transactions).
Transactions processed during the sample period, excluding vote transactions — usually the more meaningful throughput figure.
Number of slots covered by the sample period.
Length of the sample period, in seconds.
Notes
numTransactions / samplePeriodSecsgives total TPS including votes;numNonVoteTransactions / samplePeriodSecsexcludes the large, fairly constant vote-transaction load, which is usually what "network TPS" means.samplePeriodSecs / numSlotsgives the realized average slot time for the window, about 314 ms (60 / 191) in this example.
