room directory is very very slow over federation as that API doesn't let you paginate

It takes at least 90 seconds to get a room list

@erikjohnston are you seeing this performance prob?

[richvdh]

(ftr, it has never been quick. I assume it pulls the entire room list from matrix.org before responding to the client)

[erikjohnston]

yes, it is quite slow

...and it gets stuck issuing 50x's half the time :(
