The problem of slow joins isn't the client, it's the protocol. Just join the Synapse admins channel on matrix.org (will take half an hour to load, your client will time out and give you an error but it will load eventually) and the other admins will tell you they're all aware of the problem.

Shocking to see Arathorn deflecting about this. I run a server and just never use federation to avoid the problem.

Not sure why I keep getting flagged

I’m not deflecting - i’m just trying to figure out which slowness folks are complaining about. Is it really slow joins over federation (which is absolutely a real problem, which is why we’re busy implementing https://github.com/matrix-org/synapse/milestone/6). Or is it Element Android being sluggish when changing rooms? Or is it a slow server being slow to send messages?

My point was that saying “matrix is slow” is unhelpful given it’s completely unclear what aspect is being complained about.

I disagree that the protocol is the problem. There's a combination of frontend/backend issues impacting performance, but servers written in faster languages don't seem to struggle with joining channels all that much.

Synapse being written in Python seems like a much bigger problem to me. This problem only exists in rooms not already available on the server, though; if you register with matrix.org then matrix.org rooms won't suffer nearly as much as running your own server.

Sadly, alternatives like Conduit still aren't fully-featured and they probably won't ever be as focus lies on the Element ecosystem. It's a real shame.

I don't know why Arathorn is further down the thread dismissing this problem.. it's a well-known problem in the community..

https://github.com/matrix-org/synapse/issues/1211 there's the seven year old bug

Thank you for this, I was beginning to think I'm the crazy one.

Ok, so matrix is useless then, is that it?

They're talking about a specific issue with federation at scale. I run a hybrid conference in Seattle and we use Matrix. I make a successful living out of this, so it seems a stretch to call it useless.

E-mail has much bigger scale and is fast

A single email messages often takes minutes to receive. Conversations are usually highly asynchronous. I wouldn't call it fast, exactly.
