You’re right that XMPP is federated as well and Matrix can be non-federated but I’ve heard some people had trouble with the Synapse server chugging resources despite not using federation.
Comment on XMPP as a Discord alternative for small group?

You can have non-federated Matrix. And XMPP is federated as well.
XMPP is probably fine. I haven’t used it but people say it’s good.

I’ve been self-hosting Matrix Synapse for more than two years to chat friends and family and it has been rock-solid and it’s on a VPS that os hosting a Nextcloud and Lemmy instance as well. It is definitely not really resource hungry for small groups of people.
If you want to try again this route, just make sure that everybody saves a backup of their keys as the messages are all encrypted and while you can authenticate a new client installation from another client that the same user is logged in, some people - like my mother - only use one, on her phone, which is understandable.
So in summary, I’m very happy with it! :)

How much CPU, RAM and storage does it consume for you?
tsl@lemmy.stefanoprenna.com 5 months ago
That is a good point… on average it’s around 500Mb of RAM usage, between 0.5% and 1% of CPU (it’s a 2.4Mhz four cores).
Space is 5Gb, mainly media files accumulated over two years.
So overall, not bad.

Tell them to fix it that shouldn’t happen.

Yes, but Matrix a plague of questionable open-source and a metadata disaster.
Matrix is developed by a for profit entity, a group of venture capitalists and having a spec doesn’t mean everything. The way Matrix is designed is to force into jumping through hoops and kind of draw all attention to Matrix itself instead of the end result.

Stop recommending questionable open-source like Matrix. XMPP is the true and the OG federated and truly open solution that is very extensible. XMPP is tested, reliable, secure and above all a truly open standard and decentralized it just lacks some investment in better mobile clients.
What people fail to see is that XMPP is the only solution that treats messaging and video like email: just provide an address and the servers and clients will cooperate with each other in order to maintain a conversation and it can be configured to be secure and private. Everything else is just an attempt at yet another vendor lock-in. Here a quick overview of the architecture.

What also bothers me is how prominent matrix.org instance is. So you got a system that is supposed to be decentralized… Yet defederating from the one central server would break a lot.
TCB13@lemmy.world 5 months ago
That’s just another detail where we see that.

Does XMPP not have the same metadata?
poVoq@slrpnk.net 5 months ago
No, or rather not quite. XMPP is designed on a need-to-see system where basically only the meta-data that a server or client really requires to function is shared with it. This can mean that there is quite a bit of meta-data shared with various servers in a popular group-chat, but that is rather the exception.
Matrix on the other hand is designed as a replicated data-store, meaning that really everything is shared with every connected server by design. The reason for this is so that chats can continue to function even when the original server is removed etc. This was the big original selling point of Matrix, but lately they have been somewhat quiet about it as it largely contradicts privacy concerns and might even be fundamentally GDPR incompatible. In any case it is pretty much a meta-data nightmare.
LodeMike@lemmy.today 5 months ago
Well you also can’t remove shit on someone else’s email servers so is that not GDPR compatible?
TCB13@lemmy.world 5 months ago
Let me add the following: the problem is that that metadata is all over the place AND you can’t remove it from those 3rd party servers. Also there’s a ton of questionable stuff like read receipts and reactions that are never encrypted (not sure if this was fixed already). XMPP with OMEMO enables will encrypt everything.
