Thank you for your reply. In this case the Event Log Verbosity is set to be High. Extensive audit logging is not activated but only audit logging. Performance logging already is set to 5 min.
The performance degradation was obviouse about two weeks after the audit logging was activated. This server has 32 GB RAM and 12 CPU cores. Both QlikView server and Publisher are running on the same server. There are about 60 concurrent users as average on the server.
In this condition don't you think that audit logging can impact the server performance?
