Tile shader set to circles in the alpha channel of the material applied to the surface.
Hopefully this will get you by... if it needs to be fully 3d holes, you're gonna take a pretty major speed hit for sure.

you should use wesware's approach, but take it a step further by also placing the same circles shader in the bump channel to give the holes a small degree of bevel, creating the illusion of thickness

you'll need to make a few adjustments to the circle shade in the bump channel

And out the same shader into the bump channel to get the rounded edges from the paint
