Need a little help with a 2D tile map

I’m trying to make a big tile map 2D game and my first approach was a 300 x 300 tile map with a gameobject for each tile. This was very slow and I then tried to find a mother way to do it.

Then I found something about make a mesh from vertices and triangles and put a texture on it, but somehow I can’t seem to get it working okay.

Does anyone know of at tutorial or does anyone have some kind of code that can get me started?

Unity’s Tilemap implementation is in Beta, and currently set to release in Sept 2017 if all goes according to plan.
