Safari Slow in MacBook Pro

[topocalypse]

I'm opening like 7 tabs in Safari (2 of which are youtubes) and others are regular text-based pages. I also open iTunes with music on and MSN messenger. My Spec is below (MacBook Pro). Why is safari runs extremely slow and used up 1GB+ of Ram? I wouldn't have expected 4GB of Ram to run out this quickly.

anyone knows the solutions? thanks

software update, repair permissions, restart, upgrade ram or don't keep so much stuff open

or use chrome =)
