This is because IE actually has a great deal of its code spread throughout the windows O/S. The memory utilization report for IE is lower that it appears because the base browser components are already loaded into memory under other processes such as explorer. When you start loading multiple copies of the browser it becomes evident that IE isn't as efficient as it leads on to be. 1 Browser Instance with a Blank Page: firefox.exe 15.4 MB iexplore.exe 10.3 MB 2 Browser Instances with a Blank Page: firefox.exe 16.4 MB iexplore.exe 20.6 MB 2 Brower Instances pointing to www.news.com: firefox.exe 21.3 MB iexplore.exe 40.6 MB It is possible to configure IE to run as a single instance like firefox; however by default it launches multiple instances because of stability issues. The end result is significantly higher memory consumption with IE when windows is installed on a computer with more than 32MB of RAM. Even if IE runs in a single instance it would still consume more memory than firefox. ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Greg Reese Sent: Tuesday, June 29, 2004 10:13 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Web Browsers can that profile.ini file be redirected out of their profile to their home directory? One thing I noticed is that Firefox uses almost twice the memory that IE does. I opened cnn.com on one server with IE and then on another server with Firefox. IE was using around 20,000K and Firefox was using 39,000k. Could be a quirk of each server though.

Here is why: 1. It is a very tight browser, it has excellent performance. 2. It doesn't have the broad spectrum of vulnerabilities that IE has. 3. The 250MS draw delay saves bandwidth and increases end user responsiveness. By contrast IE renders the page dynamically, or you can change it to render the page in the background. Unfortunately IE draw in background results in the end users waiting for a long time for pages to display. 4. Tabbed browsing and popup blocking built-in. 5. Customizable UI. You can remove any visual element, such as a menu item, by editing the browser.xul file. This file is contained in the zip file named browser.jar. 6. The control panel is extremely simple and easy to use for end users, there are not unnecessary item in the control panel to confuse them. Administrators can customize the browsers 500+ configuration options by typing about:config in the address bar. Firefox is nicer than Mozilla as well because the salting for the profile directory is easier to handle. Mozilla uses a binary file in C:\Documents and Settings\%USERNAME%\Application Data\Mozilla called registry.dat to specify the location of the user profile. This binary file stores the full path to the profile information, meaning the username changes an you need some way to modify the path in the binary file. Firefox uses a plain text .ini file, C:\Documents and Settings\%USERNAME%\Application Data\Mozilla\Firefox\profile.ini. The path in the ini file is relative. This means that the changes you make in the profile in the default user account works properly for all users in the terminal server. Not to mention it is much easier editing the profile file. ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Jim Kenzig http://thin.net Sent: Tuesday, June 29, 2004 6:29 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Web Browsers Correct as in MOZILLA Firefox.

Personally, I like Opera a lot and use it on my laptop but it may be a little much for my users. Has anyone loaded up other browsers on Windows 2003 and what kind of problems have you run into in doing so. Thanks! Greg
