Then > how hard is it? Dear Bin, I have a processor with enabled HT and run FreeBSD 5 2. I notice that the system handles this quite well on its own. When i start to compile something then the first miniute XMMS has trouble playing MP3s, but afther that time the system has ajusted quite well. -- Alex Articles based on solutions that I use: http://www.kruijff.org/alex/index.php?dir=docs/FreeBSD/
