This topic describes the comparison results of the online transaction processing (OLTP) performance between PolarDB for MySQL and ApsaraDB RDS for MySQL in the same scenarios.

Compared with ApsaraDB RDS for MySQL, PolarDB for MySQL has been optimized in the following aspects. This improves the overall performance of clusters.
  • PolarDB for MySQL adopts leading hardware technologies, including the Optane solid-state drive (SSD) of the 3D XPoint storage medium, NVMe SSDs, and RDMA over Converged Ethernet (RoCE).
  • PolarDB for MySQL implements a set of I/O and network protocol stacks that run in user mode based on new hardware. This improves performance and reduces latency.
  • The items, such as locks, I/O paths, and large tables, are optimized at the kernel layer. This improves performance in concurrency scenarios.
Note The following services are used in the tests:
  • Dedicated PolarDB for MySQL clusters of Cluster Edition in different specifications.
  • Dedicated ApsaraDB RDS for MySQL instances of High-availability Edition in different specifications (with local SSDs).
For more information about test procedures, see OLTP performance test methods.
