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 ?
I removed the 301 response for HTTP requests (I actually wrote this server myself), restarted the server and explicitly browsed HTTP. No difference.
I'm not surprised, because, as I reported in my original message, browsing from somewhere offsite is fast, whereas browsing onsite to the same thing is not.
This cannot be anything but a routing issue (or something along the route doing deep packet inspection really inefficiently), and the XR500 remains my main suspect.
Thanks for trying, with QoS completely disabled it won't be interacting with any packets. This might be one to contact Netgear directly about as they may have seen this on their non DumaOS routers http://support.netgear.com/
