I have two questions:
Would it be significantly slower to have a class for sessions in PHP? I mean, nearly duplicate with the current $_SESSIONS, except it's handled by a class using file IO, un/serialize, cookies and so forth... I'm just having issues with how PHP handles it's sessions.
Is it bad to have lots of files in one directory? Around 50k or 60k? Should I use a database or merge them into a lesser amount of files, or is it unnecessary?
