I am facing extremely slow fetch/network on a RN 0.57 app with wifi (this has been the case since 0.4x, so i think it is version independent) I am fetching some json or downloading images with RNFS.
It happens on ios.
It happens on dev and release versions both.
It happens both when debugger is on/off.
It does not happen on cellular.
It happens both when using fetch, xmlhttprequest, (RNFS, i don't what that one uses)
It always happens on a wifi connection. (tried several networks/places)
The request takes 10-15seconds on wifi vs sub 1 second on cellular.
While not being sure, the delay partly comes from starting of the request, several seconds pass until i get first event from xmlhttp.
I am stuck and cannot find a way around this.
