I noticed one multithreaded benchmark on that page (Cinebench R10 32Bit Multi), and the difference there is a factor of 1.55, a bit more than 50% faster. (And another advantage of the SU2300 is it has vmx (vt-x) and can take 8 GB RAM.) > > The Atom will be more than enough for me.

(Hi! :) The webcamd and lirc ports have been updated now so testing a remote + sshd only setup should at least be possible for `normal' operations. (i.e. outside of things like single user mode and setting up the box.) Here is my page with links and vdr ports etc again: http://people.freebsd.org/~nox/dvb/ Juergen
