Well, this might not be the swap by itself, but simply the swap being
activated in parallel to a lot of other disk access.

Note that on most modern systems swap is not really necessary anymore
since they have more almost boundless memory (unless you want
hibernation). So one option might be to fix the problem by getting rid
of swap... ;-)

For mounts, not for swaps.

comment=systemd.automount makes little sense for swap devices, this is a NOP.
