Weird Lantency Problem

[clowwindy]

time curl -v --socks5-hostname 127.0.0.1:1080 http://www.google.com/ >/dev/null

libev local + nodejs server = 200ms
nodejs local + nodejs server = 260ms
libev local + libev server = 340ms
nodejs local + libev server > 500ms

libev local with nodejs server is fast, others are slow.

Problems may exist in nodejs local and libev server.

  else cachedPieces.push data  if stage is 4
  # remote server not connected
  # cache received buffers
  # make sure no data is lost

->

  else if stage is 4
    if not remote?
      connection.destroy() if connection
      return
    data = encryptor.encrypt data
    connection.pause() unless remote.write(data)

If the dest addr in the header is hostname， shadowsocks-libev has a minimum 200ms latency.
