simple 4mb buffer proxy benchmarks

the goal: to do fast virtual host routing, e.g. to have a single process on a machine listening on port 80 and proxying data based on HTTP Host to other non-port-80 web processes on the same machine

many people use nginx for this because nginx is faster than node is currently for data-heavy applications (see below)

about these benchmarks

they use the JS proxies from https://github.com/substack/bouncy/tree/master/bench

and this node server: https://github.com/substack/bouncy/blob/master/bench/bench.js#L11-L16

each result was generated with ab -n 5000 -c 10

nginx used is v1.4.4 w/ 256 worker connections and 1 worker process

benchmarks done on a macbook air laptop computer, all w/ local http servers

no proxy (control)

  worker_connections  256;
}

error_log /Users/max/Desktop/bench/error.log debug;

pid /Users/max/Desktop/bench/nginx.pid;

http {

  server {
    access_log  /Users/max/Desktop/bench/access.log;

    listen          8886;
    server_name     _;

source for hostproxy bench:

var hostproxy = require('hostproxy')
var net = require('net')

module.exports = function(port) {
  return hostproxy(function (host) {
    return net.connect(port, 'localhost')
  })  
}

what are you proxying to?

IMO, the best thing would be a tcp server that just returns the http response as a static buffer. Similar with the client as well.

if you look at the code in hostproxy it isn't really optimized yet at all. there's lots of unnecessary buffer slices and such but i wonder if that's even where it is spending its time. might want to get @trevnorris in here.

Not sure what is supposed to be happening here. Just taking data from point A and sending it to point B?

If that's the case then I'll write up a quick module that just opens up two points and dumps the input from on fd to the other.
