New Tab performance has varied for me on different machines and installations, sometimes being instant and snappy and sometimes needing several seconds. The greatest impact often are plugins, though, since IE still caters for plugins from the 90s by emulating appropriate events for “new browser window” when a tab is opened. Under “Manage add-ons” you can see how much load or navigation time each has.
