This topic describes the metrics that are used to test the performance of an ApsaraDB RDS for MySQL instance.
- Transactions per second (TPS)
The number of transactions that are executed by the RDS instance per second. A transaction is executed only after it is committed. Use SysBench to test the performance of online transactional processing (OLTP) for executing a read/write transaction that consists of 18 read and write SQL statements.
- Queries per second (QPS)
The number of SQL statements that are executed by the RDS instance per second. These SQL statements include INSERT, SELECT, UPDATE, and DETELE.
