One argument is too look what 9.0-RELEASE used to report. Which would be an order of magnitude less. Another argument is to try to visualize what a load of 0.20 would mean if we had a single process and a very simple kernel that wouldn't run anything ot= her than idle/scheduling and that process. Ignoring the more complex computation and taking just the arithmetic mean. = 0.20 load would mean that we would have a loop running, since it's the only proc= ess, for 20% of a minute. That means it would run for 12 seconds and sleep for = 48. I don't think that background activity is worth 12 seconds per minute. Free= BSD would have serious performance issues if it did. Yet another argument is to run something equivalent to the background activ= ity. If things were fine and it's just our perception that is wrong, then I would expect the load to double. It doesn't.. --=20 You are receiving this mail because: You are the assignee for the bug.=
