Just for comparison, my VPS server has ~20 active email boxes (postfix,dovecot,spamassassin,clamav), a few small-ish active wordpress sites (apahce,php-fpm,mariadb), radicale and some other smaller services running with 2 cores and 4GB RAM and it’s mostly just fine. Occasionally, specially during heavier updates on wordpress-sites, memory tends to get pretty full, but it’s still just fine. Tweaking memory cache for php (or running something else than php) would increase performance by a lot, but even without optimization the 5€/month VPS is quite capable to keep your internet presence around and on your own hands.


I don’t know about long term, but it’s running on my pile of virtual servers and does it’s job just fine. The openmediavault itself is a pretty good web-interface on top of Debian and it’s just configuring the underlying operating system so you can get exactly the same setup by writing configurations manually for the services. OMV is just a convenient tool to manage simple fileshares.
I use it only for samba and wireguard, so can’t really say if it’s as solid with other extensions, but for me it’s been a decent tool for the job.
