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.
