I have two NTFS partitions mounted in my filesystem. One of them hosts my projects, so it is very important.
Every so often, my computer gets sluggish, sometimes to the point of almost freezing up. I noticed that whenever that happens, the process mount.ntfs shows disk sleep in the CPU column of the System Monitor ksysguard (see screenshot below).
Notably, in those situations, the memory is not running out, and the CPUs are not running at full capacity.
What are possible explanations for this and how can I fix it?
I run Kubuntu 19.04, 64-bit.
