title: Slow extraction of data with the Bloomberg API (Matlab Datafeed Toolbox)
body: <p>I am using the Datafeed Toolbox to extract data from Bloomberg. In particular I use the <a href="https://nl.mathworks.com/help/datafeed/blp.history.html" rel="nofollow noreferrer">functions</a>:</p>
  
  <pre><code>d = history(c,s,f,fromdate,todate)
  </code></pre>
  
  <p>I found however that the data extraction is quite slow.</p>
  
  <p>E.g. for a list of 248 tickers, and for the field PX_LAST within period 1/1/2016 - 2/28/2018, it takes up to 2-3 minutes to extract the data.</p>
  
  <p>Is this an issue with my Matlab or is there a way to optimize this number?</p>
