Ratio: 1 requests an image the size of the viewport. Ratio:2 requests an 
image h*2 X w*2 so you can do some panning without redrawing the image, 
but at the cost of generating a larger image and transfering a larger 
image to the browser.

I think it defaults to something like 1.5. I always set it to 1, but 
your needs may be different.

This config parameter should do what you want:

Hi. Use singleTile:true in your WMS layer options.
