title: Does opening a link in a new window improve performance/reduce resources used in current window when compared to opening it in the same window
body: <p>There is a functionality in a web app that I'm developing wherein, DICOM images are downloaded from a server and is rendered on a web-based dicom viewer application. I'm triggering the webViewer either by using an <code>&lt;a href=".." target="_blank"&gt;</code> or with a javascript <code>window.open(...)</code>. </p>
  
  <p>Knowing that it might open in a new tab or in a new window, would it be possible that either of the possibilities is better than the other when taking into account the system resources and also the responsiveness of the original browser window?</p>
  
  <p><strong>P.S.:</strong> I'm asking this because my browser just hangs a lot when the images are downloaded into the cache(opening a in a new tab, but same window). Each image is really huge(can reach up to 700-800 mb usually)</p>
