Test metrics


Test metric	Description
QPS	The number of read and write operations that are processed per second.
Average Latency	The average latency of read or write operations. Unit: µs.
99th Percentile Latency	The maximum latency for the fastest 99% of operations. Unit: µs. For example, if the 99th percentile latency is 500 µs, 99% of operations are processed in less than 500 µs.
