<li>Top users shows you the most active users for your site.</li>
<li>Recent hits displays information about the latest activity on your site.</li>
<li>Node count displays the number of times a node has been accessed in the node\'s link section next to <em># comments</em>.</li>
<li>Popular content block creates a block that can display the day\'s top viewed content, the all time top viewed content, and the last content viewed.</li>

Enabling the log adds one database call per page displayed by Drupal.</li>
<li>Discard access logs older than allows you to configure how long an access log entry is saved, after which time it is deleted from the database table. To use this you need to run <em>cron.php</em></li>
<li>Enable node view counter allows you to turn on and off the node-counting functionality of this module. If it is turned on, an extra database query is added for each node displayed, which increments a counter.</li>
