自甲骨文之后全面普及 4Gpbs
#### 一、如何升级
创建快照，从快照中恢复机器，转移 IP 完成
#### 二、网络质的飞跃，本地 Speedtest
```
Testing download speed................................................................................
Download: 1564.00 Mbit/s
Testing upload speed......................................................................................................
Upload: 2186.79 Mbit/s
```
#### 三、网络质的飞跃，跨区域对拷

#### 五、CPU Geekbench 5
单核跑分：729
多核跑分：901
升级之后，网络太顶了。在甲骨文之后廉价机器再次被顶到 4Gbps ，其他厂商没一家能做到廉价鸡内网 4Gbps 甚至于物理机内网都做不到 4Gbps 的。
