'page daemon wakeups' counts the number of times that the pagedaemon is woken up due to a page shortage. It does not include the 5-sec wakeups. How about posting a complete 'vmstat -s'. A look at the code suggests that vm_pageout_page_stats() thinks there's a page shortage (since that's the only piece of code that will actually do anything if page daemon wakeups is zero). >Kamal R.

"Belady's anomaly" can only occur if paging really happens. -- Peter Jeremy _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
