What does it NOT test?
Really just out of boredom what runs fastest on my system.
What factors affect the score?
Other than the browser itself, the most significant factor affecting the score is the type of CPU in your PC. After that, the power of your graphics card affects the result somewhat, though mostly in situations where the card is very slow, or no drivers have been installed for it. Running other applications that consume system resources at the same time as the benchmark is running will naturally affect the score. The size of the viewable browser area also affects the score, so the screen resolution you use, the size of the browser window and whether the window is minimized affect the score as well. Beyond these, other factors are usually not significant. Your internet connection speed and network latency do not influence the score in any way.
