My laptop is a Dell Precision M4800 -- not the newest but is perfectly fast enough for what I need to do. I run KDE under X usually. Tried wayland for the first time recently and there was huge input lag with moving the mouse. I found it unusable. Other people have similar problems [1] [2]. For me at least wayland is a no go until the performance matches X.
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.
