IE8 beta 2 has been a great release so far from our Redmond friends. We should not forget that its still Beta and we will have issues with it.
I was playing around with IE8 Tab Grouping and also looking into Task Manager on how IE8 was performing.
Tab Grouping is a cool feature which gives a color for similar tabs opened from same web site. For example, you may be reading an article from a web site and suddenly you see something interesting, and click that link to open in a new tab. IE8 groups those two tabs and treats them to be different web page links from the same web site and thus gives a color to it so that we can easily identify where the tabs came from.
Most interesting is even the Quick Tabs will show that color

Suddenly I thought why not open Task Manager and see what's going on
I was surprised to see that there are 10 instances of iexplore.exe running and also to see it marked as a 32 bit application even though I have installed the 64bit version in my 64bit Vista Ultimate!
I also found that I had opened 10 Tab Groups opened (based on the color) which directly relates to 10 instances running in Task Manager!
What is happening here!
Let us do some test:
1) I opened IE8 and fired up the Task Manager
You can see that shows 2 instances running!
2) Let us open 3 tabs now
We now have 4 instances running!
3) Lets close two tabs in the previous screen-shot
I still have 4 instances running!
I really do not know what is happening here, but each instance does use memory!
What with IE7?

I have opened 4 tabs and yet I get only one instance running (This IE7 is a 32 bit version though)
Any suggestions or comments are welcome
UPDATE: This is a new feature called LCIE. To know more about LCIE, please visit here
UPDATE: Regarding the 32bit thingy, IE8 defaults to 32bit becoz so many Addons are still 32bit and dont have native 64bit versions. Thanks to Nathan Mercer for pointing it out. The 64bit executable is available from the start menu though :)
