The image used on http://wiki.openstreetmap.org/wiki/Image:Belgium-trafficsign-a25.svg for example is this png: http://wiki.openstreetmap.org/images/thumb/8/88/Belgium-trafficsign- a25.svg/640px-Belgium-trafficsign-a25.svg.png

Once the conversion from svg to png is done once at a given size, you don't see any delays, but just take an svg on the wiki and put it in a test page at a size that wasn't rendered before, and it'll take a minute before you see the image in your browser. But anyway, the svg conversion time isn't a really big problem, as that's only seen once by the person editing a wiki page who entered the image into that page. The main problems are that: * the png images which were created from svg aren't transparent anymore. This was done correctly once, so you'll see a mix of images with transparent and opaque backgrounds on http://wiki.openstreetmap.org/wiki/WikiProject_Belgium/Conventions/Traffic_Signs although they all have transparent backgrounds actually (the transparent ones were rendered before the change happened on the server and because they're cached they stay transparent, if you take one of the transparent ones and put it on a page at a different size, they'll be opaque) * The jagged appearance of some svg images like http://wiki.openstreetmap.org/wiki/Image:Belgium-trafficsign-a25.svg (this happens in every browser I have, FireFox, Konqueror, Arora) and it's in the source code of the page: (from the same page mentioned above:) <img alt="Image:Belgium-trafficsign-a25.svg" src="/images/thumb/8/88/Belgium- trafficsign-a25.svg/640px-Belgium-trafficsign-a25.svg.png" width="720" height="600" border="0" /> But the rendered png image isn't 720 by 600 pixels as it shows on the page, it's actually 640 by 533, and thus you get a stretched image which is creating the jagged appearance. I have no idea why this is, my own local mediawiki installation handles it all just fine.
