I didn&#8217;t do this before because Illustrator wouldn&#8217;t let me export a large enough image to PNG, in this case 13794 by 8192.  Instead I exported the image in two parts and collated the resulting images using <a href=\"http:\/\/www.imagemagick.org\/\">ImageMagick<\/a>.  The detail on that zoom level is high enough so that the names of side streets are now visible.<\/p>\n<p>In addition to adding the higher zoom level, I also re-rendered the tiles for levels 3 and 5 as the scale on the line strokes was off.  Surprisingly, this resulted in a 50% bandwidth savings for the level 3 tiles so they should download a little faster now.<\/p>\n<p>To further increase download speed, I have spread the tiles over four domains based on the recommendations of <a title=\"\u00e2\u20ac\u0153Optimizing page load time\u00e2\u20ac\u009d by Aaron Hopkins\" href=\"http:\/\/www.die.net\/musings\/page_load_time\/\">a study on optimising page load time<\/a>.
