OpenLayers: Tiles from Multiple Servers

# Multiple Server URLS

performance, multiple urls, request, light

Load your tiles faster by pointing to the same server, but with different urls

Browsers typically limit the number of concurrent requests to the same server, based on hostname. In order to ake tiles load more quickly, it often makes sense to distribute requests over multiple hostnames to achieve more concurrency. Typically, browsers perform best with 3 different hostnames -- your performance may vary. (For example, if your server can't handle more than 2 requests simultaneously, then additional hostnames will not help you.)
