This document summarizes benchmarks of MySQL multi-thread slave performance using different numbers of slave_parallel_workers threads on Oracle Cloud MySQL instances. It finds that using 16 threads provides the best performance, processing queries faster and keeping the slave less behind the master compared to lower thread counts. CPU usage is also lower with 16 threads even though more threads are used.
