title: Angular universal consumes a lot of cpu
body: <p>right now I am putting in place a server side rendering for my website made with angular 5.</p>
  
  <p>I managed to put angular universal in place but I encounter a problem and I absolutely can not solve it or work around it.</p>
  
  <p>I noticed that when loading the first page when we arrive on the site, it consumes a lot of cpu but during navigation once the first page loaded it consumes nothing, after doing several tests, I can even crash the website.</p>
  
  <p>I thought to cache the pages but I do not know how to do it because I need them to be dynamic according to the requests on my API ..</p>
  
  <p>So I ask you this question, is there a way to reduce the consumption of cpu or a way around this problem? thank you !</p>
