I think, homeserver software is also still somewhat immature. I'm waiting for Dendrite.

I'm evaluating Synapse (as all the other servers say they're pre-alpha incomplete) for the last week or so, but one immediate issue I had is that when I had set it up, on my home low-power NAS it required more than 15 minutes (and 0.7GiB of memory out of 1GiB I've allocated to the container) at fully-saturated single CPU core to join #matrix:matrix.org. And it took no less than a minute to join a room with just 200 participants. Sure, that's just for the first time, but it still feels way too resource-heavy, compared to other chat systems.

The machine has 10-year old Atom 330 CPU - which makes it an ancient relic, but hey, it has more than enough power to run XMPP (w/various transports), mail and web servers, and it just sits on a shelf in a kitchen, with a barely audible humming.

Synapse's readme does try to spell out that it requires at least 2GB of RAM and a recent CPU. It is absolutely resource heavy, but not showstoppingly so in general. The comparison with XMPP is dubious as the protocols are completely different: it's like comparing a local filesystem with a distributed database and complaining that the DB is slower.

That said, Dendrite should improve things a lot; we should have more stats in the near future but it seems to idle around 150MB of RAM and should run much better on ancient hardware. We are not bothering optimising synapse much further in favour of focusing on finishing Dendrite. Needless to say, we expect Dendrite to be finished well in time for the Librem 5 to go live, 18 months from now!
