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.

NOTICE:

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.
