Mhh, I once installed it as a test, but not in a production environment.

You only need to disable SMT in certain situtations (I once read a paper about
it, but I don't have the link anymore).  I can remember me that you need to
disable SMT if you need a lot of memory bandwidth.  You can enable SMT and
monitor the CPU usage.  You can disable SMT when the system is running and
monitor again to see the difference.

2 cpu's can be handy: 1 for exiration and one for the rest.
