title: Solr reload vs restart
body: <p>I am using solr-5.4.0 in my production environment(solr cloud mode) and am trying to automate the reload/restart process of the solr collections based on certain specific conditions.</p>
  
  <p>I noticed that on solr reload the thread count increases a lot there by resulting in increased latencies. So I read about reload process and came to know that while reloading</p>
  
  <p>1) Solr creates a new core internally and then assigns this core same name as the old core. Is this correct?</p>
  
  <p>2) If above is true then does solr actually create a new index internally on reload?</p>
  
  <p>3) If so then restart sounds much better than reload, or is there any better way to upload new configs on solr?</p>
  
  <p>4) Can you point me to any docs that can give me more details about this?</p>
  
  <p>Any help would be appreciated, Thank you.</p>
