And what about performance? I mean those "Auxiliary Processors" are "weaker" than the real ones, so scheduling CPU intensive processes to them makes a weird assymmetry. In average for example with a dnetc client what's better? :) Running two processes with HT turned off, or running four of them with HT on? Just curious, I do not have a HT capable machine... ----------[ Free Software ISOs - http://www.fsn.hu/?f=download ]---------- Attila Nagy e-mail: Attila.Nagy@fsn.hu Free Software Network (FSN.HU) phone @work: +361 210 1415 (194) cell.: +3630 306 6758 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
