system load is at .7, and no process's taking noticeable CPU. before I
upgraded to kernel 1.3.90, (1.2.13), load under similar conditions was .0x
if you would like system stats, let me know: basic stuff: 386dx25 w/12
megs ram, 20 megs swap.

> Yesterday I installed 1.3.95 after having used 1.3.69 for a couple
> of weeks (after I got nothing but problems somewhere in the 1.3.7x
series).
>
> This kernels looks like being stable, but I still see the funny load
> average peaks that also showed up somewhere in 1.3.7x when I tried those
> before.
> This is most apparent when running xload, but it can also be seen in
top.
> Sometimes the load just goes up to 1 or 2 without apparent reason (with
> the usual exponential ramp-up and ramp-down).
> Often the load just climbs to that level and then immediately starts
> falling down again, like:
>
> 2 - /\
> / \
> 1 - /\ / \
> / \ / \
> 0 -/ \/ \-------------

> It seems like it often happens when the X server has entered the screen
> saver while some process that displays output is on the currently active
> screen area. But this isn't the only cause for sure, I sometimes see
> the load go to 1 and stay there for half an hour while the screen is
> switched on and "top" shows no processes taking noticable CPU time.
>
> It also looks like the "noise" above the 0-level when the system is idle
> and there happens to be no load peak at the time has a higher amplitude
> than it had with older kernels.
