Is text slowing the framerates ?

I have reaced a point in my app where I try to gain as much speed as possible.
So, since I have a lot of small text labels, i was wondering if that would be better using small pre-defined sprites instead ?
Maybe using 2d meshes where the sprites are the texture…

I think Your assumptions are basicly correct. Athough i have not measured text() vs sprite(). One very slow thing i have noticed is the stroke with rect(): i always use noStroke().
