'Memory Usage' value inside Planning Analytics Administration (PAA) website seems too high (caused by misunderstanding what this value actually measures)

Troubleshooting


Problem

User launches Planning Analytics Administration (PAA) website. User clicks on the 'Administration' button. User clicks on the tab 'Databases'.
The dashboard shows all the PA instances running (in that environment). User looks at one of the PA instances, and sees that the 'Memory Usage' is higher than they expect.
Why is the memory usage so high?

Symptom

Example:
Imagine a scenario where:
  • PAA dashboard shows memory usage of instance 'tm1_supp5' to be:  2.55Gb
image-20190404080135-3
  
  • The user then looks on the PA server which is hosting the instance. Inside 'Task Manager' they can see that this service relates to PID = 13608
image-20190404080323-4
     
  • Inside tab 'Details' they look at that PID, and find that the relevant executable (tm1sd.exe) is only consuming 1.1Gb of RAM:

Why is the amount of RAM consumed by the Windows process (tm1sd.exe) less than the value shows in the PAA dashboard item 'Memory Usage'?
