Before jumping into debugging, could you check one more thing please: compare the download speed from the network and from the localhost. So in first case, download using URL http://EXTERNAL_IP:PORT/file.txt (from the same or different machine) In second, http://127.0.0.1:PORT/file.txt (from the same machine) Localhost address (127.0.0.1) could be considerably faster if TCP stack IO is an issue. If both cases are roughly the same, then the issue is elsewhere, like the file IO as you've pointed out.
