That's not a huge amount of traffic - if your DB schema is set up
properly there should be little difference compared with using files
for sessions.

If you're using PHP sessions and a database bound session handler....
The session should always be stored at the end of each request - if
you're writing the session data manually for each request then you're
doubling the workload. Also, the session will be loaded automatically
as soon as you call session_start() from your code - if (!
count($_SESSION)) then the user doesn't have a current session - no
need to refer to the database again.
