Label extension recommendations

We show a green dot with the words In Stock on all items with a quantity 1 or over. We use the Amasty label extension to do this. The problem is it kills site speed. Attached is what it does to page speed- it increases load time by about 50%. I have reached out to them but they will not help. Does anyone have another extension they can recommend? Or a simple way to build this?
