Or using unix domain sockets:

```js
const unix = require("unix-dgram");
var Syslogd = require('syslogd')
Syslogd(function(info) {
console.log("line received", info);
}, {server: unix.createSocket('unix_dgram'), unlinkSocket: true}).listen("/var/log/nginx.sock", function(err) {
console.log('start', err)
})
```

Check parser performance by `npm run performance`, which will run 500000 times
