I have been experiencing significant performance issues while using the browser on qube. The chromium based browsers perform even worse than Firefox-based browsers when playing videos. chrome suffers from severe stuttering during video playback, making it almost unusable, and I also experience lag while browsing. However, on LibreWolf, both video playback and web browsing are quite smooth.
I attempted to disable jit in the browser, thinking that performance would drop dramatically and lead to severe stuttering. In reality, chromium felt even smoother afterwards, although fullscreen video playback is still not ideal. I believe this could be due to chromium’s aggressive jit strategy causing the lag, turning off jit seemed to resolve the stuttering issues. An added benefit is that the browser’s security has greatly improved, and memory usage has decreased.
Another strategy is to disable jit deep optimization while keeping baseline jit enabled.
