Fourth, performance. mysql 8.0 also has a significant improvement in terms of performance. According to official data, its speed is faster than MySQL 57 twice as fast. Especially in high-workload and high-competition scenarios, MySQL 80 is even better. In addition, MySQL 80 also introduces the resource group feature, which allows users to optimize for specific workloads on specific hardware, further improving performance.
