Firefox is using 2.2 times the memory and one of my two processors is pegged at 100% (shows up as 50% in the task manager).
Wow. That is quite a difference. Here are my tabs from Chrome:
I notice, as I'm typing this, that Chrome does not spell check as I type. Howveer, I'm going to keep using it and see how it goes. Not ready to make it my default browser yet. What about you? Have you tried it?
EDIT: I just noticed that crome is using more memory than I originally thought. There are a lot of processes there. This is in keeping with google's stated architecture of having a seperate process for each tab.
