HZ=100 ?? vmware
Okey, I found out I need to increase the HZ=100 default in the kernel config to a higher number. I also understand it decreases system response times. So, what I need to know is the lowest setup for HZ=??? to be able to run vmware3 in full screen. I got to get rid of the rtc: 100 kern.hz prompt. Google tells me to increase to HZ=1200 but is this not too high? -- dick -- http://www.nagual.st/ -- PGP/GnuPG key: F86289CE ++ Running FreeBSD 4.10 ++ Debian GNU/Linux (Woody) + Nai tiruvantel ar vayuvantel i Valar tielyanna nu vilja ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I am not sure, but if vmware is using the same HZ setting as polling does then 1200 is not too high. If I understand it right, the HZ setting tells stuff how often to checkin to see if work needs doing. 100hz would be way too low. Every 100hz on say a 2ghz machince would requirer you to spend a lot of time on something every sec(2billion/100 per sec if I am right). Maybe nothing because you are delaying some programs that you want to execute, not pause and wait every 100hz. This would most likely slow everything down, a higher number would make things smoother and faster, but only to a point. Its kind of complicated, but when you find the right spot(somewhere in the middle) everything is good. If you had a 4ghz machince you may want an even larger number. If I am wrong I am sure there will be a followup shortly.

Re: HZ=100 ?? vmware
Hi, I run VMware3 on FreeBSD 5.2.1 fine. I use HZ=1200, and that seems to work perfect. I've tested and found that 1000, and even 1100 still gave me rtc: 100 kern.hz messages. When I set HZ=1200 I got no more of these messages.
