title: Azure SQL high wait time on "VDI_CLIENT_OTHER"
body: <p>We're benchmarking our app with different scales of an Azure SQL database, and we're having a hard time saturating the db. Among other things, we've executed this query:</p>
  
  <pre><code>SELECT *
  FROM sys.dm_os_wait_stats
  ORDER BY wait_time_ms DESC
  </code></pre>
  
  <p>The top row of the result was something like </p>
  
  <pre><code>wait_type        waiting_tasks_count    wait_time_ms    max_wait_time_ms    signal_wait_time_ms
  VDI_CLIENT_OTHER         19560           409007428          60016                37281
  </code></pre>
  
  <p>What is this wait time? What exactly have we been waiting for during those 409000 seconds (almost 5 days)? Google doesn't seem to know what <code>VDI_CLIENT_OTHER</code> is.</p>
