Files are faster, but you really only need to worry about those
microseconds on high traffic sites or if your PHP is doing heavy
lifting. Some things to think about:
* Are you on a web cluster? If so, you'll want centralized session
storage. Your options are a database or a distributed file system
(NFS or openGFS, for instance)
* Are you using a shared host? If so, it's possible for session
collision and snooping to happen when using file based sessions.
Database storage might be a good idea in this situation.
