that's certainly depend of the hardware.
it look like the udoo don't like having lot's of vertices.
i guess texturing would be faster.
I think the fastest would be to use 2 texture :
one with image of all letters, while the other correspond of the size of the text. color coding the letter number.
then a shader that use both texture to render a single primitive with all letter on the same time.
