Back in May, the Internet Explorer (IE) team left open the possibility that Microsoft might deliver a tab-responsiveness update
for those of us suffering from IE 8 tab-performance issues.
Alas, that update isn’t going to happen. Based on feedback from Windows 7 testers, Microsoft has scotched the idea. Not only is there no tab-hang reporting functionality for the IE 8 release that is built into Windows 7, but there won’t be any for us IE 8 users running Windows XP or Vista, either.
I asked Microsoft officials whether there might be some relief in sight for those of us who continue to have our well-isolated IE 8 tabs
whir endlessly and never actually open a given site. This has been a continuing problem for me on my ThinkPad X60 with 1 GB of RAM running XP — in spite of my following Microsoft’s advice to prune my IE add-ons
. Regularly, my IE 8 performance degrades by the end of a day of browsing to the point that I stop running it and switch over to Firefox or Chrome
