To support multiple cores and threads for maxim performance.

It is running on the WITI board which is based on MT7621AT with 2 cores 4 threads integrated.But ss-libev can't only use one thread.

It's quite easy to enable multiple processes like this:

ss-redir -c config.json -u -f /tmp/pid1
ss-redir -c config.json -u -f /tmp/pid2
...

Then you will get several ss-redir processes working on the same port.

This feature requires the change e921f40 and Linux kernel > 3.9.

BTW, it could even work as a load balancer for different server configs. Just make sure different processes use the same local port.
