Exactly. 100% is a core, 200% is two cores and so on.<br>

No, it does not. For that you need --cpus.<br>
For example: Defining --cpus 2 --cpulimit 100 results in processes<br>
being migrated around 2 cores with either a maximum of 50% for each<br>
core (if both cores are used at the same time) or 100% for one core<br>
(if only one core is used at the same time) or something in between.<br>
So, the resulting sum of both cores calculated does never exceed 100%<br>
(75%+25%=100%, or 10%+90%=100%, and so on...).<br>

- --iolimit limits both, read and write. Read and write are combined.<br>
But(!), --iolimit never limits cached read/writes, only direct access<br>
or flushed data/access.<br>
