因爲本人技術低微，就直接發日常了。
看到論壇說是swap開機，我興趣就來了嗷，這不補貨了，就衝了。
價格很寄。PP手續費甚至50%以上，最後想了想反正也是玩具，支付寶6.7左右拿下。

上來就是一個大坑嗷，機器默認鏡像裏面甚至連ssh都沒有。
哦，原來你們自己知道自己沒有ssh啊還寫個教程，咋就不能鏡像默認安裝呢？

VNC進入

apk update && apk add openssh-server && rc-update add sshd
echo "PermitRootLogin yes">>/etc/ssh/sshd_config
service sshd start

這樣就可以根據另一篇教程連接IPv4的ssh，如果跳板機或本地有IPv6的話，也可以直接連接IPv6的22端口上ssh了

上來第一步，free -h，真貴物啊，真就32G機器開了16G的swap

              total        used        free      shared  buff/cache   available
Mem:          31.3G       27.9G      340.5M        2.0G        3.0G       60.0M
Swap:         16.0G      598.3M       15.4G

接下來就是喜聞樂見的speedtest：

先裝speedtest：apk add speedtest-cli

Retrieving speedtest.net configuration...
Testing from OVH SAS (192.99.x.x)...
Retrieving speedtest.net server list...
Selecting best server based on ping...
Hosted by Bell Mobility (Ottawa, ON) [352.23 km]: 2.46 ms

第一眼：OVH，好，我知道這玩意垃圾了。

第二眼，沒想到啊沒想到，經典内存不夠直接kill，後來試了把pre-allocate關閉也不行，估計是内存太小太小了，而且OVZ也不能自建swap。好，直接開個機器去測iperf3：

[  5]   0.00-10.00  sec  16.2 MBytes  13.6 Mbits/sec                  receiver

而我在測試的時候看到了這麽一行：snd_tcp_congestion bbr，好家夥，好歹給你bbr了（樂）

但是，顯然IPv4早被屮爛了，可惜無法看到有多爛。

只能説，經典的OVH（

YABS直接跳過了硬盤檢測，因爲小於2G
