I also faced performance issues with Ubuntu on my desktop, but I managed to significantly improve it with a few optimizations. For example, installing the `preload` service, which preloads frequently used libraries into memory, makes a huge difference in switching between applications.
Lowering the `swappiness` value to 10 in swap settings and enabling `zramswap` on SSDs also reduced system freezes. Switching to a lightweight desktop environment like XFCE instead of GNOME was a real lifesaver in terms of performance—especially on an 8GB RAM system, where I observed up to a 30% improvement in performance.
