I'm not sure if you are serving static HTML, but in the off chance that you are rewriting your URLs and there is some server on the back end doing the crunching that could affect the start render time. Especially if you are on a dev box and the server is less powerful. You have a relatively long Time To First Byte if this is just static HTML, so either it's your server or the network I would guess.
How can the server side latency affect the start render time after the html and css has been completely downloaded? I understand server side latency may contribute to things such as time to first byte, but how would the url rewriting affect the start render time at the point when it has already downloaded the html and css? I ask because the url rewrite by definition is processed before the html can be downloaded and thus is part of the time to first byte time. However, if you look at the test output you can see the html and css are completely downloaded about 500 ms before the start render time kicks in, and all http requests after those two elements and before the start render time are product images, which should have no affect themselves on the start render time.
So, to be clear, i am wondering why there is a 500 ms delay between the html and css downloading, and completion, and the actual start of the rendering.
As a side note, i am using a duplicate account on one of our live servers. We have two servers for load balancing (using the least connection method for balancing) and failover, so the performance shown by the test will show the real world performance pretty accurately.
