Appflowy has extremely poor performance. Both in terms of loading large files and RAM usage. See my performance comparison of block editors[1]:<p>I've built a block editor using Qt C++ and QML that is vastly more performant[2].<p>As you can see, Appflowy probably even has a memory leak, causing the memory to grow indefinitely in my test.<p>[1] <a href="https://imgur.com/ZL5QCS0" rel="nofollow noreferrer">https://imgur.com/ZL5QCS0</a><p>[2] <a href="https://www.get-plume.com/" rel="nofollow noreferrer">https://www.get-plume.com/</a>
