    Hi,

    I have a 190+ user environment with 2 T1 circuits going out to the internet.
    My users sometime complain that their internet connections are slow. All of
    them are running on IE6 at the present time. I'm planning to upgrade
    everyone to IE8 and I am considering things like accelerators, smartscreen
    filter, etc. Does anyone know what kind of a performance degredation I can
    experience from enabling some of these features that were not available in
    IE6?

    Seems to me that you need more T1 capacity.

    Slow down, cowboy! Has WinXP SP3 been installed on all of these computers

    Hi,

    Most of these machines are still running on SP2. Can this make a difference?

    Thanks,
    JeffH

    I used to have 5 people on 2Mbps SDSL (which is similar to having 2 x T1)
    and would occassionally gets complaints about it being slow, often due to
    users downloading large files. Having 190+ on 2 T1 circuits is going to run
    slow if the bandwidth is being saturated, it doesn't matter what software is
    running on the clients.

    I guess I put out too much information. Does anyone know what kind of
    performance hit I can expect from activating things like accelerators versus
    not activating those features.

    Thanks,

    Your issue is more likely the fact that T1's aren't as fast all the time,
    depending on the traffic and the ISP. They may not be providing the actual
    bandwidth you think, and if it's shared T1s, that can slow things down.

    Changing browsers isn't necessarily going to speed things up.

    You're asking a far too generic question.

    Most accelerators I've seen are simply a way to add a GUI element, such as
    being able to select words in a page and pass them to another URL. In those
    cases you will zero performance impact on the connection because nothing is
    passed at the time the page is retrieved. It may benefit because it might
    save one click.

    Smartscreen is a different matter - each site visited requires a call the
    smart screen URL. It's very tiny amounts of data though, so again impact may
    well be neglible.

    Unfortunately the only way to find out if it will impact your connection is
    to test it, which means upgrading everyone.

    You also need to consider a few other things - the number of simultaneous
    connections made the browser, for instance.

    On the whole though, given that you already appear to have a major
    bottleneck, impact from upgrading IE should be the least of your worries.

    Tom,

    Thanks for your reply. I'm not looking to increase speed I'm mostly
    concerned with slowing things down by deploying a group policy that enables
    accelerators. I guess that the only way to see what performance I may get is
    to test, test, test.

    Thanks,
    JefH

    Looks like you're not having much luck getting your question answered.
    I've wondered the same thing and think I even posted here once
    wondering about it. But then I have a mere 25 at my biggest site.
    Haven't done the exacting testing needed to answer it. Just ended up
    using my own best guesses. I assume the smart screen filtering uses a
    little bandwidth but may be worth it. Likewise AVG and others has
    search filtering that checks each link in search results and flags any
    it knows are bad. I assume that's the same system only multiplied, so
    I turn that off. If they go to a bad link it should get flagged by
    screen filtering at that point. Accelerators I assumed do some pre-
    fetching but maybe not. If you're actually able to get some data on
    this it would be great to hear about it.

    What Tom said.

    No, installing SP3 probably won't make a difference but there are a few
    important things for you to consider:

    1. If you install IE8 (or IE7) and then install SP3, you won't be able to
    uninstall IE8 (or IE7), should the need arise, unless you first uninstall
    SP3. See http://blogs.msdn.com/ie/archive/2008/05/05/ie-and-xpsp3.aspx

    2. Support for WinXP (x86) SP2 ends on 13 July 2010. After that date,
    computers running WinXP (x86) SP2 "will no longer receive software updates
    from Windows Update" unless and until SP3 is installed. Extended Support
    for Windows XP SP3 will continue through 08 April 2014.

    • What does it mean if my version of Windows is no longer supported?
