Internet Explorer 8 (IE8) vs. Internet Explorer 7 (IE7) (Performance)
August 27, 2008
I’ve some great news for Internet Explorer users. While IE8 Beta 1 had some performance improvements over IE7, it was not enough and developers knew that. As a result, they’ve made Internet Explorer 8 even faster. As it says:
Some of the tests we have done show pure JScript performance improvements up to 2.5 times. We also measured the performance gains on common Gmail operations, like loading the inbox (34%), opening a conversation (45%) and opening a thread (27%) compared to IE7.
I think that it’s a great improvement and Internet Explorer 8 Final will probably be even faster.
Now here’s what else IE 8 is going to offer:
Scripting Improvements
Memory Management Improvements
Networking Improvements
Rendering Engine Improvements
New Developer Features
Data URI
Selectors API
JSON
and much more.
