I'm not aware of any systematic comparison of memory consumption for
MapInfo, QGIS and ArcGIS
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.
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)
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.
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.

Hi,
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)?
Also, is it possible to set a limit on the total RAM QGIS can use in
the settings? Is it the cache size?
Thanks in advance,
Paul
