Why are android editors so slow when files get bigger ?

It's maybe not really a TC editor specific problem, but I noticed that many editors on Android are really really painfully slow when files are bigger than a few kB. Scrolling becomes close to impossible, with reaction times of one second between each scroll.

I'm using Android 4.0 and 4.4 on two different systems, same in both cases.

They probably all use the same edit control from Android, and this control becomes very slow with big files. That's why I had to limit the size to 1MB when loading. Btw, the control on Windows Phone is even worse. I have considered to write my own control, but it is a LOT of work, and it's not guaranteed that it will work any better.
