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:
As is well documented, IE 6 is notoriously bad at leaking memory, particularly due to circular references that include COM objects. The good news is that our tests indicate that this problem has been solved in IE 7. While in our test profile, it appears to consume more memory than Firefox, IE 7 seems to have solved the horrendous memory leaks exhibited in IE 6.
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.
