verry high load, clean install, debian etch, ispcp rc 5

[robin]

I have setup a new server (opteron quad core, 4 GB RAM, 2x 500 GB) running debian etch with AMD64 smp kernel and ispcp rc5. The problem is that even with a single user on the server it causes verry high load:

Its a quad core so 400% is actually 100% load but still load is generated when i open up a single webpage, that cant't be normal? Its not only apache but also mysql or other services like amavis that take a verry high lad all of a sudden? I don't think it is a ispcp problem does anyone has a clue in what direction i have to look? Its a clean install i have no idea,any help is welcome
