From the logs Engine>Trace>System_Engine.txt i got the records which mention,
"QrsSecurityManagement: Retrieved privileges in xx ms from the QRS"
What is privleges means here? Is it section access or retrieving privileges from Security rules for app?
In some cases i saw consecutive records of this. Why does Qlik retrieve this info for same user and app three times?
Also i saw some records of this which takes retrieve info +300000ms which equals 5minute.
