title: GAE Go runtime 1.11 needs more instances than runtime 1.9. It this common?
body: <p>Since we migrated from go 1.9 to go 1.11 as Google required, we notice that GAE needs the double or triple amount of instances to handle the same traffic.</p>
  
  <p>The code logic is pretty much the same because we don't have time to rewrite the application with Go 1.12 yet. We are still using <code>google.golang.org/appengine</code> instead of the new SDK.</p>
  
  <p>I just want to know if others have a similar experience?</p>
