Slow local traffic with XR500

Setup : internet modem -> router (XR500) -> computer 'M' -> VM on 'M'. VM runs web server. Web server has a 5 MB gzipped page for index.html. A domain name 'D' is mapped to the WAN address of the modem.

Now If I browse to 'D's index.html locally, it takes a pathetic 50 seconds (100 KB/sec according to a separate wget). If I browse from a remote location, it's in in 5 seconds !

What up ? This started when I changed my old Netgear router (JNR3000) to the new one (XR500). QOS switched OFF.

This is a mystery. How can local traffic (which never even gets on Internet in this case) be slower than remote ?

Any clues ?

Thanks.

What Firmware is currently loaded?
What is the Mfr and model# of the ISP modem the NG router is connected too?

  How are you accessing the local site specifically? Are you using HTTPS? If so is it faster using HTTP?

    I simply browse the domain name with Firefox. It's all HTTPS. If HTTP is used, it is automatically redirected to HTTPS.

  Firmware V2.3.2.40
  The modem is a Ziggo 'Connect box', no doubt it is rebadged but I can't find relevant info. They used to be Zyxel brand modems.
