What are you trying to measure? Measuring perf is a very difficult problem, and frankly most browser benchmarks don't mean a whole lot to the end user experience.

There are Javascript tests where now IE/Firefox/Chrome are all so close most users could never tell them apart.

There are rendering perf tests where IE9 will destroy the competition (today), but there aren't many websites that really take advantage of it.

There are standards tests where even a mediocre score frankly is good enough, but all the major players are near-perfect now.

Measuring memory use doesn't mean a whole lot either, and actually measuring memory accurrately is super difficult.

 

I simply want to gauge or compare the browsers on my home and work computers to see which has the perceived "quickest" experience for browsing. I'm doing nothing scientific, nor anything useful to anyone else who does use my computers

 

That sounds like a great idea, Microsoft has such a strong history of releasing IE Beta's after they have been completely tested and after all security concerns have been addressed...oh wait, that's not accurate.

 

Oddly enough the reviews have been that this is one of the most refined and finished BETA applications that Microsoft has released. From my one day of playing with it, I'm actually very impressed.
