Title:
** Description changed:
I have a ssd/hdd system where the ssd is used for the system and most of
home is on a large hdd.
I noticed that the weekly fstrim cron job slows the system down considerable,
including e.g. firefox and
the desktop. iotop reports:
otal DISK READ :
It's not really that surprising -- it needs to iterate over the mounts,
find free blocks, and tell the disk controller to trim them; on a
developer machine where there is usually a lot of data turnaround over a
week, this usually has to process dozens of GB.
