:I'm not sure if this is -current fodder or not, but since it's still
:happening in -current, I'll ask.
:
:We recently upgraded a server from 2.2.8 to 4.0(the same behavior is shown
:on 5.0-current, too). Before, with the exact same load, we'd see load
:averages from between 0.20 and 0.30. Now, we're getting:
:
:load averages: 4.16, 4.23, 4.66
:
:Top shows the same CPU percentages, just a much higher load average for the
:same work being done. Did the load average calculation change, or something
:with the scheduler differ? Customers are complaining that the load average
:is too high, which is kinda silly, since 4.0 seems noticably faster in some
:cases.
:
:Any ideas?

:Kevin
I believe the load average was changed quite a while ago to reflect not
only runnable processes but also processes stuck in disk-wait. It's
a more accurate measure of load.
