JScript Performance in Internet Explorer 8 Beta

The cat’s finally out of the bag. IE 8 Beta is finally live and available publically for download. Here is a link to the blog post JScript in Internet Explorer 8 Beta 1 for Developers detailing the work done by the JScript team.


Here are a first few set of comments that I found around the performance of JScript engine that is shipped as a part of IE8 Beta.


·         John Resig’s post -  JavaScript in Internet Explorer 8, wherein he states “… Internet Explorer 8 is our release…”;  “…The IE team has made some big improvements in improving garbage collection issues, memory management, and performance - all of which will be greatly appreciated in everyday applications…” - http://ejohn.org/blog/javascript-in-internet-explorer-8/


·         “…In fact, it seems IE8 can go toe-to-toe with Opera 9.5 build 9815…” - http://thomas.tanreisoftware.com/?p=89


·         “…As for performance, it runs a javascript test I ran before 4 times faster than IE7…” - http://forums.majorgeeks.com/showpost.php?p=1118324&postcount=4


·         “It feels fast. I have no data to back this up, but everything feels snappier. Not just script performance but page rendering as well…” - http://www.dzone.com/links/internet_explorer_8_beta_1_first_impressions.html


·         “… pages seemed to load at about the same speed or a little bit faster as compared to IE7…” -  http://www.webware.com/8301-1_109-9887147-2.html?part=rss&tag=feed&subj=Webware


 Would add more as we go along.
