<p>Hi Radek,</p>
<p>In that case would you please create an issue at hub.qgis.org and add your finding, e.g. rendering in QGIS 2.8 takes xx seconds, and xx seconds in 2.16.</p>
<p>You'd also need to upload your data and projects (both in 2.8 version and 2.16 version).</p>
<p>This will give developers the chance to investigate.</p>
<p>Andreas</p>

<p>Hi Radek,</p>
<p>Is this about data that resides locally on your machine or from a network drive?</p>
