IE7: Twice as performant as IE6, but half as slow as FF 1.5

Ross Dargahi of Zimbra complained about IE 6 performance. Since IE 7 is here, he decided to retry his tests and see how Microsoft had done:

“We also looked at the performance of Firefox, IE 6, and IE 7 over a set of common ZWC operations such as logging in, viewing messages, navigating around various folders, viewing contacts, and performing various calendar operations.

In conclusion, IE 7 has made some quite significant improvements over IE 6, both in terms of performance and memory management; however, there is still room to improve – particularly against Firefox, a challenge I hope the IE team will be taking up.”
