 CLIENT:   -mtu 1400 -sndwnd 256 -rcvwnd 2048 -mode fast2 -dscp 46
-其它带宽请按比例降低窗口，比如50M ADSL，把CLIENT的 -sndwnd -rcvwnd减掉一半,SERVER不变

+> Snappy is a compression/decompression library. It does not aim for maximum
+> compression, or compatibility with any other compression library; instead,
+> it aims for very high speeds and reasonable compression. For instance,

+> for most inputs, but the resulting compressed files are anywhere from 20% to
+> 100% bigger.
