Since you are also using 32bit you also may be affected by the database setting:

> Syncthing v1.3.0 has introduced a database tuning enhancement. This is not a fast machine (dual core and spinning HDD) so I’m used to slow scan times - but after 5 hours Syncthing still has not finished scanning. I noticed that there are 1000s of very small .ldb files (~ 300 bytes) and every second 20 or more are created. I don’t know how this .ldb thing works and if these files are just temporary. The folder that is currently scanned has lots of small files, maybe this is the reason? Or is it…
and our great devs have already implemented a fix for the next version

until then you need to set it manually to “small” after updating to v1.3
