<p>Hi René Luc,</p>
<p>Good points. I also had a look at these stats and was disappointed.</p>
<p>So I agree that it would be worth-wile working on improving the performance of QGIS server version 3.</p>
<p>On the QgsProject loading performance issue: is this only an issue at the first loading of the project or every time a request is being made?</p>
<p>Definitely I would welcome a submission at the next round of QGIS grants to further study the issues and improve perfomance were possible.</p>
<p>Thanks for your thoughts,</p>
<p>Andreas</p>
