[Qgis-user] Hardware comparisons

[Bo Victor Thomsen]

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.
