Lately I've experienced a lot of disk i/o, it seemed that my disk was always working. This really bothered me.. so I tried to track it down.. Using some dtrace magic the problem seems to come from safari.
This is the newest safari (4.0.1) on leopard. It seems to read/write about 3 mb per 5 sec constantly after opening the first web-page. A freshly restarted safari (viewing about:blank) doesn't do any io, but after I load the first page (for example google.com) it starts trashing disk in the background. It's really annoying and eats battery..
Anyone else seeing this?
