I believe you are referring to the memory reservations QlikView makes in system memory - the Low Working Set and High Working Set configurations in QMC > System > Setup > QlikView Server > QVS@ > Performance tab?
The Low Working Set is the threshold at which QlikView will continue to cache results, not attempting to purge these cached results, until the threshold is breached. Have you experienced unplanned QVS restarts and seen warnings in the QVS Events log referring to virtual memory? If not, then I don't believe you would need to add more memory RAM at this time (Although, more RAM wouldn't hurt anything either ).
Hope this helps,
Thx for you reply.
I haven't no QVS errors linked to memory usage. I just want to understand something.
Referring to the memory chart displayed in Windows Resource Monitor, there is "In Use", "Stand By" and "Free" memory.
My question : is QV used & cached memory displayed in "in use" memory (in windows resource monitor), or QV used memory is displayed in "in use" and cached in "StandBy" ?
