I've seen many charts like that - in most of them it appears like readahead isn't helping at all. > Why does bootchart stop before all the *really* slow desktop stuff starts? There's some rework needed to make it stop in the same way that e.g. the readahead collector works - right now it just runs for 20 seconds or so and exits. This is on my work list to fix. > Why does bootchart claim an idle time of ~5 sec, not that I wouldn't > like that, but .... :) That's when the CPU are below a certain percentage(somewhere below 1%) for a certain time (0.5sec)... enough to call "idle". Usually this happens when there is really slow IO. It bears no correlation to the systemd state.
