I have a MacBook with 4GB, and Chrome takes so much RAM it brings my macbook to a juddering swapping halt. I usually have about 20-30 tabs open which i need for reference, and even with AdBlock and Flashblock, they are taking nearly 3GB of RAM. Just a new blank tab takes over 30MB, a tab with this thread open takes 60MB, a tab open to Ars Technica takes over 220MB. Quitting Chrome gives me about 2-3GB back. When I reload Chrome, I can watch in Activity Monitor as all 3GB of free memory vanishes within a few seconds. Any help? I'm running a Macbook 2.2GHZ, 4GB ram, latest Chrome 15.
