Start Render Help

[kartes]

I was wondering if I could get some insight into the Start Render times and how they are reported through WebPagetest. Here's an example of our test results:

http://www.webpagetest.org/result/120106_34_2RW6A/

According to the results on our First View, the Start Render time is over 10.6 seconds. However, when I clear out my browser cache and access our site directly from my local browser, the whole page is loaded in about 2 seconds, similar to the Repeat View results.

Whenever I use WebPageTest at various locations around the world, the Start Render time is consistently around 10 seconds on First View and the Repeat View is similar to what I experience when using my own browser.

Any thoughts or suggestions? Thanks for your help.
