    HTTP latency for IP address range

    When trying to download content from a particular site, it is really slow. This problem only shows up for any sites that fall within a range of IP addresses that the web server is hosted on. Going through a proxy server from different countries, there appears to be no problem. I've done a traceroute and everything appears fine. The problem clearly has to do with HTTP, has nothing to do with the host server and probably isn't a problem with any of the routers along the way, although it can't be entirely ruled out.
    That leaves me with the impression that my LAN or local router is having problem with the HTTP content. I have no firewall active. If I attempt to download a 550 kb text file from the remote server, it takes nearly a minute to complete and you can see it downloading in chunks.
    The problem shows up in all browsers.
    If the problem has something to do with my LAN or computer, I'm stumped as to figure out how to locate the problem. The problem is only within a certain range of IP addresses and you cannot see a problem with Ping or traceroute, meaning that it is not a TCP/IP problem but a HTTP problem. Where can I look to figure out what is causing the latency?

    Sounds like an Auto negotiation issue with either the servers to the switch or inter switch and the traffic is being reduced by this

    Is it possible that a router/switch is simply overloaded with traffic? But if that were true, I would see it with traceroute. Traceroute does periodically show a timeout for a server along its path but what I am seeing are large periods of latency between chunks of data being returned.

    Yes, highly possible depending on the volumes of traffic.
