 ## Features
 * Super fast and low resource consume (thanks to [libuv](https://github.com/joyent/libuv)), it can run very smoothly on almost any VPS. 
 * Fully compatible to other port of shadowsocks. 
+* Support the latest RC4 encryption method. 
 
 ## Attention
 This is an initial release and may not considered very stable, please open an issue if you encounter any bugs. Be sure to attach the error message so I can identify it.

+Do not use `-static` to compile this project. The problem is that `libuv` is using `pthread` and `getaddrinfo(3)` for async DNS resolve. But this will cause `getaddrinfo(3)` Segment Fault.

 ## Performance
 I did not fully benchmark it yet, but according to my use on [TinyVZ](http://tinyvz.com/) (OpenVZ 128M RAM and CentOS 5.8 x86). When streaming YouTube 1080p vedio at about 20Mbit/s bandwidth, it use at most 3% of RAM (RSS about 7500) and almost no CPU time. During webpage browse it use less than 0.7% RAM (RSS about 1164). Which can be considered effective.
