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
yet?

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?
