I have traced the problem with the site being slow to one of the advertising services that eFront uses. (DoubleClick)
eFront rotates banners from different services, and when a DoubleClick service banner pops up the page slows to a crawl.
I have notified eFront and they let me know that a ton of their websites have been complaining about the problem and hope to have it corrected soon.
I'll let you know when I receive any updates.
