Optimization cleanup to avoid calls related to extended slow query log stats when this feature is disabled. Bug fixed #1123921 (Alexey Kopytov).

The staticsrv_pass_corrupt_tablevariable could share CPU cache lines with InnoDB row counters, which resulted in high false sharing effect in high-concurrent workloads. Bug fixed #1125259 (Alexey Kopytov).

我可能太土包了,么看出比mysql性能好在哪。。。

优化innodb 估计大数据innodb才能对比出来吧

不过, 其实这些为什么不直接提供到mysql官方代码呢, 优化下就搞个分支
