3、系统信息
cpu为AMD 3950X处理器。磁盘IO也很给力，用speed测试，商家标注为500M带宽，看来带宽较为宽裕。
3、cpu、内存，磁盘测试等
这里测试这些杂项，看看数据。机房位于洛杉矶，上面的脚本测试有误。

cpu线程测试等。看得出来amd，确实很yes

在测一下磁盘IO
iperf3测试，这是欧洲地区的网络测试，速度很不错。
Speed测试上下行跑满，服务器带宽应该限制在500M
4、路由测试
回程和ion的回程一样，都是走的联通。和商家标注的一样。
电信回程，走的都是联通回国，出现403，不知道是不所有防御的原因。

联通去程
路由回程总结
5、路由掉包
三网状况良好。测试时间18点30——19点30
6、全国ping
测试时间19点30。
7、Unix bench Mark
不废话，看看cpu性能，直接上Unix bench Mark，单核1885，双核3202，其实这里的核实质是超线程的意思：
8、最后
tabbycloud是新的国人商家，购买与否自行斟酌，如果要购买建议月付。如果用来建站，那你需要天级备份。
机器总结：AMD 3950X处理器，NVME硬盘，三网去程直连，回程联通，线路不错，机器性能优秀。
