Internet Explorer 7 Consumes RAM
This is a personal observation of Internet Explorer 7 on both a desktop and laptop. Both these machines have ample RAM. IE 7 is problematic on resources on both these machines.
The decline in memory resources begins at approximately the ten minute mark. This is with only a couple of tabs opened. Even closing all tabs except one does not release the RAM. It requires closing IE7 completely and beginning a completely new session. Beyond the two hour mark, so much of the machines resources are claimed by the browser that the speed of the machine is decreased significantly.
These observations are not a one time impression. Data were collected over ten days. Once IE7 was closed, the computer resumed its usual speed. I will add that I have used IE7 as downloaded, without any additional tweaks. Modifications should not be necessary. Just this RAM issue along is enough for me to steer clear of IE7.

Hello,
Could it be that the problem is one which has been resolved in a subsequent patch or update for Microsoft Internet Explorer 7?
Also, have you checked to see if the problem might be due to a conflict with any security software resident on the computer? I have seen problems similar to the one you reported due to this reason.
Regards,

I operate with my entire system drive virtualized (ShadowSurfer) and have IE 7 fully patched. Every so often, I will have a two hour session and have noticed no fall off in performance.
Perhaps Aryeh has raised issues you might take a look at. Heaven knows, if you do this stuff long enough, sooner or later one sees all kinds of compatibility issues.

Thanks Aryeh and Jon,
IE7 is patched and up to date. There is nothing unusual on the machines in terms of firewall or anti-virus. I have checked for malware and spyware, with even a hijackthis log taken and reviewed.
This consumption of resources does not happen at this rate with either Opera or Firefox. The reason that I was having a look at IE7 was that this was brought up to me as a problem that more and more people were finding with the new version of IE.
Thanks again for your suggestions; and Jon, thanks for the reminder about ShadowSurfer.

You are correct, Forsythe, IE7 definitely has issues. I regularly have to restart it because it locks up on me while surfing. I had always just assumed that it was corrupting itself by overwriting addresses improperly.

[...] Haven’t tried this myself, is not very easy now that I’ve completely crossover Mac and I only use IE to test Websites about once every week, but it seems that IE is a memory thief. [...]

Hi Catherine,
I use IE7 extensively and there are not usually any problems such as you describe.
There is a memory leak there clearly. Tracking it down though is another matter sadly. Try reinstalling the latest version and see if it will give you a choice of repairing the installation.
Regretably, it could be caused by a conflict, possibly with some security software where something has got corrupted. Installing many progs all over again will not be fun for you.
Has this only recently started happing? If so, using “System Restore” might geti it back on it’s feet.
If it’s fairly recent, can you think of anything installed around the same time?
I have seen this with RAM Defragmenters – I don’t suppose one of them is installed is it?
Good luck with it anyway!

I noticed the slow down also, on a clean install of Windows XP with all available Microsoft updates. At first I thought the evil giant was slowing down XP intentionally so Vista looked relatively fast! Probably not though because once I installed Firefox and used that exclusively, the slow down was gone.

Catherine,
Could you give more details regarding the configuration that you are using?
I would like to see if we would see these potential problems in our organisation aswell.

You are correct. I formatted my HD, reinstalled XP Pro, then downloaded every update Microsoft had, and IE7 will still eat my memory to the point where I get Virtual Memory messages if I don’t close it.

yeah ie7 is the biggest consumer of memeory on my computer,
right now ie7 is using 376Mb of memory
(3 instances of ie7, 11 tabs total)
while system is using 74Mb
and explorer is using 36Mb
i think i’ll try firefox or opera or if i’m really desperate chrome
