Let us know.

I'd have GUESSED that MySQL would have just cached something that
small and oft-used in RAM anyway, so a MySQL memory engine table
wouldn't perform any better than the MySQL half of things.

Better than the File System, probably, though that also may be getting
cached...

It won't be any better than your own file-system calls, but you could do:

<?php
  session_start();
  //read-write $_SESSION here
  session_write_close();
  //don't touch session here
?>

And it probably won't be any worse than the locking you presumably
already have in your code...

WHy is it sometimes MySQL and sometims file system?
