Since I want to draw more than 10000 font textures, how to write that shader

beginners
#1

I’d like to draw more than 10000 font textures, so I would like you to tell me how to write that shader.

setup

ofVboMesh vboMesh;
myFont.load("Futura.ttc",8,true,true,true,0.5,1000);
vboMesh = myFont.getStringMesh("taketori", 0, 0);

draw

myFont.getFontTexture().bind();
vboMesh.draw();
myFont.getFontTexture().unbind();

I want to draw plenty of textures of fonts written like this, but if you do with 1000 CPUs, FPS will go down if you draw 1000 pieces.
So, is there a way to draw textures to the shader to draw over 10000?

Since GLSL is a beginner, please tell me in detail.

I would like you to tell me if there is any better way than this.
For example, how to write a shader when drawing a large number of characters
