It was Graviton. As a result, they update some lines of their EC2 instances with new postfix “g” (e.g. m6g.small, r5g.nano, etc.). In their review and presentation, AWS showed impressive results that it is faster in some benchmarks up to 20 percent. On the other hand, some reviewers said that Graviton does not show any significant results and, in some cases, showed fewer performance results than Intel.

We decided to investigate it and do our research regarding Graviton performance, comparing it with other CPUs (Intel and AMD) directly for MySQL.

This “small”, “medium”, and “large” splitting is just synthetic names for better reviewing depends on the amount of vCPu per EC2 There would be four graphs for each test:

From pic.0.1, we can see that there was no DISK I/O activity during tests, only CPU activity. The main activity with disks was during the DB creation stage.
