title: Nginx responses static files for too long time
body: <p>For some unexpected reason, my nginx server responses static files (like <code>.css</code> and <code>.js</code>) for too long time. For example, there are some connected scripts and stylesheets on page with filesize less than 10kb. Chrome devtools timeline profiling shows, that those files are downloaded for about 15+ seconds (see screenshot below). </p>

  <p>What can be a reason for responsing static files such a long time?</p>
  
  <blockquote>
    <p>Important update. I noticed, that it happens only on html pages. If to
    open any js or css file singulary, it loads fastly, as it's actually
    expected.</p>

  <p>I use <em>nginx+apache</em> bundle on my server, and nginx is responsible for all the static files, such as js, css, images and etc..</p>
  
  <p>Thx in advance.</p>
