我曾在今年7月多上了华为云的双核4G1M学生机，当时是s2.large.2而且只有广州数据中心，今天，我再次进入华为云的学生优惠页，发现我居然还能买2x4g学生机，活动内容基本一样，但这次不同的是，型号变成了t6.large.2，而且有上海、北京可选（现在还有云数据库可供选购），因为我腾讯和阿里的机子都在上海，所以这次我上了北京的年付车
首先，说一下s2.large.2和t6.large.2的区别
可以看出，t6有性能限制，超过基准就要算CPU积分，积分用完就会强制限制到基准（积分啥的我完全搞不懂）
直接放跑分结果把，虽然不是在一个地区，但应该还是有参考性的
这是s2的，性能还过得去，就是不知道为什么speedtest跑不动
