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.
