It feel= s like I/O takes more time, and graphics are sluggish (very sientific, I kno= w, but for instance git operations are much slower after a resume). I know t= here's been an update to acpica between my system updates, when this started= to happen, but I haven't had time to revert that update and test again. I w= ill try to do that and report back. Maybe a stupid question, but did you check the cpu frequency before and afte= r suspend/resume? (sysctl dev.cpu) Best, Michael
