About IOPS

The input/output operations per second (IOPS) supported by RDS for MySQL depends on the I/O performance of Elastic Volume Service (EVS) disks. For details, see Disk Types and Performance in the Elastic Volume Service Service Overview.

Test Data

The Maximum Connections (Stress Testing) columns in the following tables indicate the results of the RDS performance stress testing. For running services on the live network, set the parameter max_connections.
