Well I should have read the first comment before I went ahead with update and reboot😪

Is it fast on a raspberry pi?

15w Raspberry pi 4 + HDDs

It did took me a week ,but I’m running one for 4years on a raspberry pi 4, it works good enough to share files and sync contacts and calendar.

This one works , I myself have done it cause my shitty isp needs a huge payment for a static public ip. A 5$ VPS was much cheaper . Server behind NAT I can help if you got any doubts
