Calculation of Internet browse time
By default, a database job calculates Internet browse time at 2 a.m. for the previous day’s activity. This is a memory-, processor-, and disk I/O-intensive activity. If you don’t use Internet browse time to manage your users’ web browsing activity, consider disabling Internet browse time to improve the performance of your reporting system.
For information on configuring Internet browse time, refer to “Configuring Internet browse time options” in the Administrator Help for your web protection solution.
