The Performance tab manages the control of the current document, including load balancing, preloading, concurrent session access, and audit logging.
Sessions
Maximum Number of Concurrent Sessions
To choose a maximum number of concurrent sessions towards the current document, enter the desired number in this text box. An empty field means no limit.
Maximum Inactive Session Time
User sessions, which have had no activity during a specified time limit, can be configured to be closed by the QVS. To set the session timeout, enter a suitable figure in this text box.
Being left empty or set to 0 means no limit.
Document Timeout
Open documents take up valuable system resources (that is, memory space, RAM, is allocated) and should not be allowed to remain open when not in use. However, if a document is closed too quickly, the users may get longer delay times when accessing the document, because the server has to reopen it. This value controls for how long a document will be allowed to be unused before the QlikView Server (QVS) closes the document and reclaims the resources.
