TTFB more than Start Render. Is this valid?

RE: TTFB more than Start Render. Is this valid?

was your test running on the same machine, same browser all the time?

Remember JS, CSS execution time depends on client machine's CPU and memory.
I also notice that walmart's base page is running on HTTP/2 protocol.
Does walmart still have HTTP/1.1? If yes, you might want to try if this can be reproduced on HTTP/1.1.

But my main concern is that why the page stays blank for 2 seconds based on my test below.
there are 20 assets contribute to the blank page.
there is a huge JS file (almost 0.5MB despite it's already compressed) on line 10 taking 1.5s to download + execution time.
I would suggest you profile all JS files that are in the the first 2 seconds.

I suggest to use Windows Performance Toolkit (free from Microsoft) to do JS profiling and do it on a medium size machine with warm cache.
