I see two problems: all tiles seem to have transparent-supporting shader (which requires a lot of additional operations like sorting) and you have 41 batches in this simple image meaning Unity has to use a lot of dynamic batching. You don’t unite tiles into single mesh, do you?
Thanks for your response, I just added tile as single sprite to scene.I will abandon the use of transparent on my sprites and i will try learn how to unite sprites into single mesh .
