HTML5 and TextField performance

Haxe
#1

I have noticed that if I avoided updating text in each frame, FPS will increase about +10 FPS more.
But I have to update the text always due to my app nature, is there any recommendation to avoid performance loss when updating text in TextField class in HTML5?

You could use multiple TextFields and swap them out, if the different values switch between multiple known values (such as 0-10). Is it one of a few common values, or is it always totally different?

In HTML5 you can also use -Ddom, and DIV-based text should be cheaper than canvas

Text always changes in non-known values.
Can I use DIV-based text while using -Dcanvas?

It is, but not integrated in the display list. You would have to use js.Browser APIs to create or move the element over the OpenFL canvas element
