<p>I'm not aware of any systematic comparison of memory consumption
for MapInfo, QGIS and ArcGIS</p>
<p>On my Windows 10 (64 bit / 48 GB Ram) QGIS consumes around 200 MB
on startup. And around 400 MB with a (for me) typical QGIS
scenario with 10 GeoPackage based layers and a WMS. I do not find
that excessive. <br>
<br>
One possible explanation for the memory usage. QGIS uses the
user-specific "appdata" directory extensively by default. So this
directory has to accessible on the app-server. This operation
might consume some memory (This is just a guess) <br>
</p>
<p>AFAIK, there no method to restrict Remote App (RDS) memory usage
on Windows Server. It's the underlying OS assignment to toggle the
compute resources.</p>
<p>Being a little bit snarky: The list price for one (1) "MapInfo
Pro Standard Concurrent Permanent" (The necessary license for MI
on Remote app-servers) is $5.887. That amount of money will get
you ca. 0.5 TB ECC ram to a server class PC. <br>

<p class="MsoNormal">We were doing some testing for using GIS
applications as RemoteApp solutions today and I noticed that
QGIS seems to be pretty RAM hungry compared with say MapInfo.
Does anyone know if there are any good summaries available
showing the differences in RAM/CPU use comparing all the big
ones (i.e. QGIS, MapInfo, ArcMap etc)? <o:p>
</o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Also, is it possible to set a limit on the
total RAM QGIS can use in the settings? Is it the cache size?<o:p></o:p></p>
