you must live in your own world scalability means it can handle a growing load, this *may be* done by spread the load over more servers good and really scalable software scales also by add hardware like memory or CPU's to the same machine and in this context doing disk IO instead use a tmpfs for sessions is exactly the opposite you would want well, finally the db-sessions become your bottleneck by mysql deadlocks if you have too much users resulting in *a lot* of concurrency on the same, shared table been there, done that, what you *not* want is a growing amount of writing queries on a database under real load
