To test the performance of concurrent downloading, it would be preferable to have a larger target website. For this reason, we will use the Alexa list, which tracks the top one million most popular websites according to users who have installed the Alexa Toolbar. Only a small percentage of people use this browser plugin, so the data is not authoritative, but it's fine for our purposes and gives us a larger list to crawl.

These top one million web pages can be browsed on the Alexa website at http://www.alexa.com/topsites. Additionally, a compressed spreadsheet of this list is available at http://s3.amazonaws.com/alexa-static/top-1m.csv.zip, so scraping Alexa is not necessary.
