You can set a minimum size below which a label representation is not drawn. This can significantly speed up rendering of the map when there are many visible objects with label representations, by omitting labels when they become too small to be readable. You set the minimum label size with a custom attribute in the header of the SVG.

To configure this feature, use an SVG with the "minSize" attribute and specify the size in "device independent" browser pixels (these are not the same as native pixels, so the same number will work for "retina" class displays as for desktops). For example:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
				<!-- Created with Inkscape (http://www.inkscape.org/) -->
				<svg
				xmlns="http://www.w3.org/2000/svg"
				version="1.2"
				width="1675.3929"
				height="909.06171"
				id="svg2"
				minSize="60">
				...
		</svg>
