That is KDE’s Wayland implementation. If you find safari slow, http is not at fault. Other browsers might be fast - or in this case: gnome, wlroots based ones like sway often improve performance. For what it’s worth, KDE is quite behind in terms of wayland. It has gotten a lot better, but it is not a good fit for evaluating wayland itself.
