<p>Hi Virag,</p>
<p>This depends a bit on the data sources used in the project (files vs databases vs web services).</p>
<p>But in general, VPN connections with a high latency are not recommended and will result in really bad user experience. QGIS does a lot if I/O when opening layers and working with databases. A low latency in your network is crucial for having a good user experience.</p>
<p>If you run into such issues, I recommend using a remote desktop solution (such as RDP, Citrix) and make sure that the QGIS desktop application runs in the same local network like your database / data source - so that the latency between QGIS desktop and your data sources is minimized.</p>
<p>BTW: other GIS will have the same issue. For example ESRI ArcGIS desktop wouldn't perform well in such a situation.</p>
<p>Greetings,</p>
<p>Andreas</p>
