title: Connecting to many databases at once in mongo/mongoose
body: <p>We are trying to connect to 1500 databases using mongoose but it's too slow to create 1500 connection with 1500 DB using this command</p>
  
  <pre><code>mongoose.createConnection(url);
  </code></pre>
  
  <p>the 1500 DB are on the same database server.
  it took more than 50 minutes to establish these connections.</p>
  
  <p>Is there any way to decrease the amount of time or is there a way to connect to the 1500 DB at once as they are on the same server?</p>
