I've always been intrigued by the promise of Matrix, have tried it out multiple times in a span of 5 years. I see it getting adopted by a few open source communities as well, and last I checked they were working on a golang implementation of the core server. However everytime my issue has been it's very slow. Curious what do you use it for ?

historically Matrix has been painfully slow, but these days Matrix 2.0 is in dev which outperforms Discord & co. https://matrix.org/blog/2023/09/matrix-2-0/ has more details
