title: Gatsby Large Site
body: <p>Our site is currently on Drupal7.  It is approaching 400k pages.  Articles and product listing. We primary rely on SEO for traffic. </p>
  
  <p>We would like to move to a more modern platform and would like to decouple our CMS from our frontend.</p>
  
  <p>I'm leaning towards prismic.io as an editorial CMS our products are in a seperate DB.  My understanding is that Gatsby can help unify different data sources so that they are treated the same in the front end.</p>
  
  <p>I also like the speed Gatsby gives you.  It is pretty impressive.  </p>
  
  <p>I've heard react isn't the best for SEO, but have read on Gatsby's site that this isn't the case.</p>
  
  <p>I've read that Gatsby stinks with large sites though.  Could take 30+ mins to generate the pages.</p>
  
  <p>Hearing all of this... Is Gatsby a good choice? Are there ways to decrease build times, what? Should I be considering a different platform?</p>
  
  <p>Thanks</p>
