I haven't used it myself but you can take a look at the Governance Dashboard and QlikView Expressor.
Actually, through Audit logs the Governance Dashboard does allow you to see the following actions (by user and by timestamp):
- Bookmarks selected
- Sheets selected
- Fields (and values) selected
- Reports, Exports, Prints, SendToExcel, and Maximize
Using the Audit timestamp from the Audit log chart in the Governance Dashboard, you could create a very basic interpolation of the timing of actions, though this would not include actual "response time". Just time in between user actions.
Additional detail, including time spent on pages, clicking within objects, etc. is currently not possible with QlikView log files (11.2 SR4 and older).
