Hypothesize #1 size of static files.

 For image files this worked, but still some font and CSS file were causing these problems.

Hypothesize #2   turning off the buffering. [--picked]

Adding proxy_buffering off;to Django block since we are using white noise for static file serving.

This might solve the issue of file size, but if this issue is due to transfer between Django and nginx, we might have to look into web app.

Solution
turning proxy buffering solved the issue, but there are still load time issues.
