Hm so the HT apparently helps a bit...  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.)

 Weren't you the one that asked about vdr on FreeBSD some time ago?
(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:
