systemd-cgtop always has "-" in both Input/s and Output/s columns. There are no spikes, even under a high disk load. I was testing it with "dd if=/dev/sda of=/dev/null". Here's the output: Control Group Tasks %CPU Memory Input/s Output/s / 214 101.5 3.7G - - user.slice 15 99.6 2.9G - - system.slice 97 0.4 95.4M - - I tried the following settings in /etc/systemd/system.conf: DefaultIOAccounting=yes DefaultBlockIOAccounting=yes But it didn't help. Any help would be appreciated. -- Vladimir Mokrozub
