- <p>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.)</p>
