Yes, this makes sense.
But then you may then also want to figure out the high cpu consumption of
those cards, to not interrupt more important workloads?
I saw there's a new version posted, I didn't see an explanation of the cpu
consumption issue mentioned. Meanwhile I also see that the docs/ update is
missing.
Would you consider adding both by replying to the new version?
