Google数据洞察-JavaScript加载优化

Question

I have a problem with optimizing my page load time. I moved my script code at end of the page, but I still have a problem with rendering blocking the download of the JavaScript files.

I checked my site in Firebug and I get this:

Why is my code loaded before images and other elements within the page if that code is included at the end of the page?

Answer 1

Your issue is that the load time of the page request (the first one in the list) takes ~1.5 seconds - more precisely the server response time - which delays all the other requests.

So regarding the graph you need to check why the server needs that long to process the page request.

Note that the page request returns the HTML of the page, which then needs to be parsed first. And after it is parsed, the other requests are started.
