Hi, I have a pc with a pentium4 cpu with HT support running FreeBSD 6-STABLE.
In the GENERIC kernel, SMP is turned off by default. I am wondering whether it is useful to enable HT-support.
In the usenet discussions, I have seen a lot about the HT security flaw that was detected a while ago. Also I read about some rumours saying that the system performance decreases with HT enabled in freebsd, because freebsd thinks that there are 2 physical cpu's and adapts the workload over them in a way that is not suitable for just one physical HT processor.
Could someone give advice on whether it's wise to enable HT-support in 6-STABLE?
And, is the following correct: enabling SMP (=HT in this case?) is nothing more than adding "options SMP" to the kernel config file and then do a kernel rebuild & reinstall ?
And what about the scheduler? Is the usage of ULE recommended, or should i stick the old one?
(I can't find that much in the handbook about HT/SMP) thanks in advance for your time and help, Niek _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-smp To unsubscribe, send any mail to "[EMAIL PROTECTED]"
