In fact, Tampa fared better in measurements taken more recently, though results have not been published. Minneapolis, Cincinnati and Detroit were at the bottom in January. The shortest and fastest way between two places may be a straight line. But that's not how the Internet works, Shklar said.

Keynote has computers around the world that it uses in its testing. Some cities have more than one, but the company keeps only one in Tampa. Every hour between 5 a.m. and 9 p.m., it automatically measures the time to access and download 40 Web sites. Each site is downloaded four times an hour, with computers connected to high-speed T1 phone lines. Keynote then calculates an average response time for each site.
