Ever since lion there has been a weird problem I've noticed on my Macbook Pro and my iMac, both do the same thing.

When I'm in a video chat on iChat with 3 people, it'll run around 25% CPU, give or take. However, once the 4th person is in it jumps to 100% CPU and everything starts running super slow until that 4th person leaves. I never had this problem on Snow Leopard so what's the problem?
