Since simple-obfs is no longer maintained, I have been planning to upgrade the services I use, and recently I started to disconnect from the process of searching for information, so I decided to find time to study it. Here is the quick process of service upgrade and the trampling records.

In October last year, I bought a small OpenVZ architecture host in Los Angeles with 768M memory, and Kcptun was configured in early November when the speed was increased from 100Kb/s to 1.7Mb/s. At the same time, it also brings several inconvenient problems like the retransmission rate is high, which is a little better than the bilateral tools such as Finalspeed, bug it is still much higher than the simple use of Shadowsocks. In addition, as a bilateral acceleration tool on Android, Kcptun is still easy to install on the client, but there are some obstacles on Linux and Windows. It is often not working properly after the lock screen or the network is reconnected.

I bought HostUS’s $16 annual OpenVZ architecture VPS. I chose LA and connected directly to the US via Shanghai. There is nothing to blame on the line. The delay is about 200ms, which is also within the acceptable range. However, the speed is only 100+Kb/S, and it is better to make a refund or change the machine room.
