: :> I have made a patchset available for both -current and -stable on my site: :> http://apollo.backplane.com/FreeBSD4/ :> sysctl -w vm.debug_pageout_stats=1 :> The debugging code prints a line to dmesg and /var/log/messages each :> time the pageout daemon runs a scan, and tells you how many clean pages, :[...] :> This output would be invaluable to me coming from people who still have :> major performance problems on heavily loaded machines. :> :> I would appreciate wide testing, especially by anyone running heavily :> loaded -stable boxes. I am especially interested in how this patchset :> performs on news boxes. : :Okay, I'm gathering data as we speak, but, would you still want to see :this data from a news box, if I had *not* been noticing major performance :problems, just to have some numbers to drool over? : :Regardless, I'll keep running the patchset on this lightly-loaded news :box (-stable) which seems to be pretty responsive... : :thanks! :barry bouwsma, lame-duck newsmangler at tele danmark internet Well, sure! Ego-stuffing is what we programmers live for :-) What I would be most interested in on your particular system is how this patchset performs with your madvise() hack removed and comparing that with your original numbers (prior to when you add the madvise()). -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
