Which version of IE? It's a long-known fact that IE isn't exactly the most stellar of browsers, but I'd be somewhat surprised if there was such a huge lag in modern versions.
Hmm, I cannot imagine IE11 running into some of the same issues that earlier versions did with performance, but you never know... I only use Windows an IE for testing but I haven't run into a serious performance issue yet.
Have you used the JavaScript console to find out exactly where the lag is occurring?
Using jQuery is a wise move. In many cases where there are known browser issues, it will compensate and try to do things the best way for that browser.
