Whenever I have a tab open with Hotmail running in Chrome, it takes up a large chunk of memory (around 250 M). I've had the account for a long time, so I have a ton of email messages stored in it. I'm assuming the Hotmail interface is caching a significant number of messages to allow for fast opening, though I've never found any evidence to back this up.
Is there a setting in Hotmail to prevent it from caching so many messages all at once?
