Don't worry about performance due to many divs. Unless you use hundreds of divs (e.g. to simulate rounded borders on some browsers), the bottleneck for webpage is and will be the inet connection.
Not at all.
That is, relatively, a small amount of divs.
Browser rendering performance is extremely impressive these days, so the major bottleneck will be the speed of the Internet connection downloading the page.
The smaller you can make your page the faster it will download and render.
