Hi all,
In QMC there is a configuration setting to set the lower and upper working set for RAM usage by the Cache. By default it is 70% and 90% respectively.
How do we interpret this setting, if there are many concurrent users will it actually take up 90% of the RAM usage? Each QVW will also need RAM for its in-memory data, which will take priority?
Attached below are the reference notes from the Qlik reference manual:
Working Set %
This control sets the minimum and maximum of the physical amount of RAM
that can be used by an application. This way it is possible to control if an
application can be swapped out of physical memory or not. However, there are
no guarantees that the operating system can serve the process with the amount
of memory set here.
Using too high settings will degrade the performance of other processes on the
computer, this may however be desirable if the computer is dedicated for Qlik-
View.
Do not change these settings unless you are well acquainted with Windows
Virtual Memory Manager! Read more about working sets in the Microsoft Windows
documentation.
The settings are:
Low
sets the minimum amount of memory, in percentage, to be allocated to the
application/process.
High
sets the maximum amount of memory, in percentage, to be allocated to the
application/process.
Cache
sets the amount of memory, in percentage, to be used as cache for the application/
process.
