This topic describes the test results of performance-enhanced instances of ApsaraDB for Redis Enhanced Edition (Tair) in different test settings.

Note The read performance is more optimal than the write performance. This is because the write performance is affected by multiple factors, such as master-replica synchronization, the AOF refresh method, and whether audit logging is enabled.

Test metrics

Test metric Description
QPS The number of read and write requests that are processed per second.
Latency The average latency for a specified proportion of operations. Unit: ms. For example, 70.33% <= 0.6 milliseconds specifies that 70.33% of the operations are processed within 0.6 milliseconds.
