Benchmarks (hev-socks5-tunnel vs xjasonlyu-tun2socks)

[heiher]

It seems that the performance of tun2socks is really good due to the support of multi-threading, but it needs more CPU usage.

[xjasonlyu]

It's inevitable to consume more CPU since tun2socks uses a user-space netstack and multithreading underlying. BTW, gVisor is constantly updating its tcpip stack and improving performance, so I would not worry about the high CPU usage for now.

[heiher]

Try to running your tun2socks on single CPU thread, It looks faster than on multi-threads for some cases.
