Data reload performance issue when using ConvertToLocalTime() function in Qlik Sense and QlikView
You might have encountered a performance degrade for data reloads when using the function ConvertToLocalTime() only with one parameter "timestamp" since upgrade to QS Feb 2021 or/and QV 12.60 as reloads could take 3 times longer than with the previous version before the upgrade.
Qlik Sense February 2021, May 2021
QlikView 12.60, 12.60 SR1
Using the second parameter "place" in ConvertToLocalTime() improves the reload performance.
The described behaviour is related to a defect. The fix is was delivered for Qlik Sense Client Managed in November 2021 IR, August 2021 Patch 14, May 2021 Patch 9 and February 2021 Patch 14.
