banger First check your drive supports trim with
lsblk --discard
Check for non-zero values of DISC-GRAN (discard granularity) and DISC-MAX (discard max bytes) columns to verify TRIM support.
As I understand it the current 4.6 iso did not have trim enabled by default, check if it does with
sudo systemctl status fstrim.timer
SSD trim can be enabled in Solus with
sudo systemctl enable fstrim.timer
If you want manual control
sudo fstrim --all or sudo fstrim -a will trim all mounted SSDs
and
sudo fstrim -v /
will display an output of what has been done.
More configuration details can be shown with
fstrim -h
