Opening documents in QlikView Desktop 12 and later uses more resources while the document is loaded. The consumption goes back to normal when the document is done loading.
See Data compression different in QlikView 12 than in QlikView 11
for details. Environment:
QlikView 12.00 and 12.10
QlikView 12.20 (November 2017) and up
When the data in the document is loaded in Qlikview 12 it is transposed from row wise (as it's stored in file) to column wise (as it's used in memory). While the transposing takes place Qlikview needs double the memory of the size of the data, causing the spike.
This is per design. The only thing to be done is to optimize the design of the document.
