(In reply to robert spitzenpfeil from comment #10) > > Something is VERY wrong with your computer. yes: it's running opensuse tumbleweed. SCNR:-( did you read and thought about my comment #5? any comments about this? > time sudo /usr/sbin/depmod ... did you notice that I've never used "sudo" in my examples ? so your example is different. let's try to compare apples with apples... so I tried your example and SURPRISE (all runnning as root as before): # time sudo /usr/sbin/depmod -F /boot/System.map-5.3.12-1-default -ae 5.3.12-1-defaut 5.725 0m5.725s real, 5.447 user, 0.276 sys, 99.95 cpu # time /usr/sbin/depmod -F /boot/System.map-5.3.12-1-default -ae 5.3.12-1-default 2> /dev/null 141.370 2m21.370s real, 39.274 user, 102.088 sys, 100.00 cpu I have no clue (yet!) what's going on -- but it's an interesting point for more investigations and tests! so thanks a lot for this hint!! and no, I still do not believe and see no evidence that this is related to my hardware (other then having 10-100 times too (s)low single cpu core performace as I would like to have;) looks like I have to dig deeper and find the subtle difference between "time sudo /usr/sbin/depmod" and "time /usr/sbin/depmod" "strace" is one of my good friends -- but this will take some more time;-( stay tuned!
