I am observing a strange pattern here. After I suspend to and resume
from sleep, the system is generally sluggish. It is not always noticable
when typing, but sometime already observable when using the mouse. It is
definitely noticeable when playing, say, frozen-bubble.
CPU usage does not indicate anything running in the background. My blind
guess is that some hardware is misbehaving after the resume and causing
lots of interrupts.
Does anyone else observe similar issues or have a hint what the cause

thanks for the hint. I’m not sure if my measurements are very accurate,
but I do see some difference. RES seems to be higher, for example, as
well as interrupt 45 (ok, that is eth0, that might just an artefact of
when I am measuring the interrupts).
Attached my script; not very good, but may be useful for others
