MySQL Computing Path Optimization

Application scenario: MySQL read-only OLTP scenarios

Technical principles: Hotspot functions related to record matching and character set processing are optimized at the code level to improve the calculation and comparison efficiency of programs. In addition, the unaligned memory access optimization policies on x86 is migrated to the Arm architecture to improve the performance and efficiency of programs in processing unaligned data.

Performance metric: Sysbench read-only tests show that the performance of Percona-Server 5.7.44-53 running on a container with 8 vCPU and 16 GB memory can be improved by about 10%.
