@c.calciumlabs.comOn my machine it's consuming about 0.5% - 1.0% of cpu time, which is higher than zerotier in the same machine (almost zero).
Tailscale does a lot more things than just tunneling though. For example, on default installation it'll catch all outbound dns request on the machine and route them through MagicDNS (100.100.100.100).
Whelp, nextcloud isn't known for being fast. I don't have hundreds of thousands of emails yet so I can't comment on that, but one thing for sure is as you put more and more data on it, you'll have to add more CPU and RAM to it or it'll getting more and more sluggish.
I haven't noticed any performance issue so far. I think they use wasm which help with speed. Too bad it's not open source, but the fact it's developed by a single guy working on it full time is actually very interesting, considering the webapp is actually work better than some apps developed by bigger teams. It can even edit PDF and gif!
I think using container instead of VM should be better for maximizing resource utilization in a raspberry pi. Instead of partitioning your tiny 8gb RAM into 3-4 VMs with even tinier RAM each, you can run a dozen of containers and probably still have some free RAM.
Believe it or not, NextCloud. It actually can work as an email client. And it can sync calendars, contacts and todo list too.
At least for Lemmy, you can "force" it to sync a particular post or comment by pasting the url into your instance's search bar.
I always look for excuses to get more servers, so if you ask me, I'd say yes, get that new server. There's no such thing as having too much servers since there are so many things I want to self-host.
I also regularly tear down my servers and see how fast I can set it up again. Keep my deployment scripts up to date.
It has happened before with the .ly domains about a year before the US invasion of Libya. Tech companies were scrambling to find a solution back then. Presumably they struck a backroom deal with the Syrian government.
