Inodes issue can be solved by:
- delete all the junk files that were created (probably outside the public_html directory of your hosting)
- use the following Cron Job Command:
wget -O /dev/null https://yourwebsite.com/public/schedule/run/your-admin-password
The junk files you are referring to are junk because you didn't use the correct Cron Job Command. It is safe to delete.
Be careful not to delete any core system/server files.
If you have 20 stores and the 3000-4000 items are distributed among these 20 stores, then there should not be any issues (Foodomaa can easily handle 400 items per store)
DO NOT keep more than 400 items on each store or else performance will take a hit.
I did some tests on your website and everything seems to be working fine in regards to the speed and performance.
And by the way, you are running Foodomaa on a very older version 2.4.1? (That's about 7 months old)
There have been literally thousands of changes in Foodomaa.
