    Intermittent web-page display slowdown

    We are getting intermittent problems where we type a URL into a browser and press enter, or click on a link, and there is a significant wait before anything happens. Occasionally the browser will 'time out', and you have to press retry, whereupon it will normally display the webpage.

    I've tried changing the DNS server addresses in the router (blueyonder -> Virgin Media -> OpenDNS), but there seems to be no difference between them. PINGing all these DNS servers gives the usual 14ms-20ms response times, as expected.

    The cable company's Technical Support say there's nothing wrong with the cable modem, and have clevgerly suggested that I temporaily replace the router by an ordinary laptop to see if this makes a difference. (Yes it does, it means that everyone yells at me...)

    At present I am trying PING/TRACERT to an arbitary site at approximately 1 minute intervals, to see if anything turns up.

    Has anyone any suggestions about what else I can do to diagnose where the problem is located (which I repeat is intermittent, but very obvious when it happens)?

    Thanks!

    One thing worth trying is to note down the IP address of some sites that you commonly access, then next time the problem happens try accessing sites by IP address instead of by name. This will conclusively prove / eliminate the idea that it is a DNS issue.

    I've seen delays like that to be the fault of the AV or firewall software. But that's not too hard to rule out by temporarily disabling one or both to see if it goes away.

    Yes, I've been doing this, with inconsistent results. And doing PING and TraceRt every minute or so to a site both using full URL or IP address.

    It may be that cacheing is having an effect after the first time?

    I don't see that AV software will impact on any of the tests I've been doing, and I don't have any software firewalls on the PCs at work.

    It's not an issue w/ an oversized host file or spyware software slowing things down?

    Thanks for that suggestion - I had the Spybot hosts file present, but changed it to the usual virtually empty one, but with no result, even after a reboot.

    However I have noticed that in Firefox, there can be a l o n g wait (several seconds) after pressing Enter, with the message at the bottom-left of the screen saying;
    Looking up <xxx.yyy.co.uk>

    I presume this points to DNS? BTW it's not Firefox-related, because everyone else, who use IE7, also complain of the slowth.

    Hrmm... I'm stretching now - not sure if this would affect both FF and IE but - how big is your index.dat file?

    Not sure if they have anything that'll help you out - but it's worth a shot!
