It feels like I/O takes more time, and graphics are sluggish (very sientific, I know, but for instance git operations are much slower after a resume). I know there'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 will try to do that and report back. > > Maybe a stupid question, but did you check the cpu frequency before and after suspend/resume? (sysctl dev.cpu) As far as I can tell, the frequency remains the same. I looked at dev.cpu.0.freq, if there's any other sysctl to look at as well, please let me know. Regards -- Niclas
