title: HiLo vs Identity?
body: <p>This is the same question as: <a href="https://stackoverflow.com/questions/803872/hilo-or-identity">HiLo or identity?</a></p>
  
  <p>Let's take the database of this site as an example.</p>
  
  <p>Lets say that the site has the following tables: </p>
  
  <ul>
  <li>Posts.</li>
  <li>Votes.</li>
  <li>Comments.</li>
  </ul>
  
  <p>What is the best strategy to use for it: </p>
  
  <p>Identity - which is more common.</p>
  
  <p>OR</p>
  
  <p>HiLo - which give best performance.</p>
  
  <p><strong>Edit:</strong> if HiLo is the best, how the structure of the DB would be?</p>
