首先参考 https://www.92k.xin/?p=21 同时我们在原来装MYSQL8的机器上面，用GCC 9.3.0 来完成Nginx的编译工作。
我们先上两个版本的效果图
两台虚拟机都是8核 4G，ab压测下，先上压测结果。

我们来综合对比下
| IP | GCC版本 | 无ka | ka | 50%无ka | 50%有ka |
| 192.168.1.101 | 4.8.3 | 1743.81 | 9444.33 | 2776ms | 263ms |
| 192.168.1.105 | 9.3.1 | 1851.51 | 8480.82 | 2651ms | 349ms |
总结：各有千秋，版本高的不一定效果好。这只是一次随机压测的对比结果，效果没有权威性，童鞋们可以多压测几次，然后求平均值，总而达到严谨的结果。
