Record live Web pages and use them for local performance testing!
Use local DNS and HTTP(S) proxies to captures your live traffic. Then use these captures in order to replay the same exact content, making sure that your tests get consistent results, that are not affected by the origin servers, the network, etc.
Check out the getting started guide or take a look at the architecture diagram.
