If you don't understand why these are faster then you need to look at the source code and benchmarks.

Qwik is faster because it splits every single reactive element into a loader that only hydrates exactly what is needed when its used, that's why its good on low ping environemnts but can be very bad on high ping environments regarless of DL speed.

Svelte is faster because it uses signals under the hood, has tons of optimizations, doesn't use VDOM, and has a much better diffing algorithm to only update what is needed.

Yes you can make react "fast enough" noone is denying that. Its used by millions of websites. That does not change the fact that all of these other frameworks are faster than it at doing the same operations/dif changes.
