The slow start could be a symptom of a failing storage device. At my work, before SSD’s were common, most users were issued name-brand laptops that would become sluggish at end-of-warranty plus a few days, due to drives making multiple read attempts on some blocks. IT bought new disks by the carton to replace the hard disks. Fortunately prompt replacement meant very little data were lost, but the cost in lost time to users and IT staff was significant.
You can use the Gnome DIsks utility to check the status of your storage device(s).
