@Oceane We have indeed been optimising the speed of both the backend and UI, glad it is bearing fruit 馃槄
The other milestone we're working on is federation, for which we introduced 3 different settings: github.com/bonfire-networks/...
Currently federation is locked down on here while we optimise some more things (like limiting how many replies are automatically fetched in threads) and then we'll change it to on-demand.
