新！Google Cloud Arm实例Tau T2A 预览测试

前文提到Google Cloud已发布Arm实例Tau T2A，目前已进入预览版阶段，因此站长也是第一时间去Google Cloud后台开通了一个实例，目前预览阶段是免实例费用的，流量费仍然在计费，使用时需要注意。

我开通的是1vCPU、4G内存的最低实例类型，硬盘我给了50G，在实际使用当中，选择debian系的发行版可能对性能的释放更有帮助。大部分开源的应用和软件，作者一般会照顾到Arm架构稳定运行的需求，除了一些厂商不太愿意公布出来的，比如Swoole Loader的Arm版，居然就只能对高级版才能下载到库文件，简直是吭爹的货。

说这么多，来看看 yabs.sh 测试结果：

路由跟踪什么的就不测了，和其他实例类型的网络都是一样的，取决于你选择的区域。
