Twitter IE6 Warning Why Internet Explorer will kill your memory   Part I

Most customers have delayed the upgrade to Internet Explorer 7 or 8 as long as possible. The reason is memory / CPU usage especially on Terminal Servers, but this applies to personal computers and VDI as well. Some of the biggest web pages in Norway have been promoting upgrades similar to YouTube and Twitter and now the Norwegian Center for Information Protection strongly recommend to upgrade. So Internet Explorer 6 is approaching its end of life and it’s time to move on.

A lot of projects these days are focusing on server consolidation leveraging virtualization to get more users on each hosts. Planning and Proof Of Concept is the essential to success. Don’t believe everything you hear about increasing user density / server by four times, avoiding purchase of additional hardware.

Okay, if you move your 3-5 year old Citrix environment to a hypervisor and stick to Citrix Presentation Server 4, Office 2000/2003 and Internet Explorer 6, maybe you will make it. What normally happens when you do projects like this, you upgrade to Citrix XenApp 5.0, Office 2007 SP2 and Internet Explorer 7 or 8 as well.

In this first post I will show you what happens with your memory usage when you upgrade Internet Explorer (IE). I have tested all the different versions of IE on 13 different web pages. The tests have been run on Windows 2003 SP2 and every IE version have been patched with the latest updates. IE have been open and closed after 1 minute and the memory usage have been recorded. The latest version of Adobe Flash / Shockwave and Sun Java have been installed with the Core Applications FrameWork.

Memory Usage :

Increase in Percentage :

Internet Explorer Performance 021 300x180 Why Internet Explorer will kill your memory   Part I

Excel Spreadsheet :

Internet Explorer Performance 03 300x117 Why Internet Explorer will kill your memory   Part I

From these numbers you can easily see that upgrading only Internet Explorer will have a huge impact on the maximum users per Terminal Server. In the next article in this blog series I will show you what you can do to reduce the memory usage with registry tuning and Citrix HDX Mediastream for Flash.
