That seems like a good idea right?

No, because all you'll get is a canned response. here's the response I received (which did absolutely nothing BTW):
Hi Joe,
Thanks for contacting us. We recommend clearing your game cache prior to your play session as the game relies heavily on your system's memory.
a. In the XMB home menu, go to (Game) > [Game Data Utility].
Important: Make sure you select [Game Data Utility]. Do NOT select [Saved Data Utility], as this will delete all of your saved games files.
b. Highlight the game data utility file (i.e., name of a particular game you have been playing) you wish to delete.
c. Press the button and select [Delete].
d. Highlight "Yes" and press the button to confirm the deletion.
e. A message indicating the file is being deleted will appear.
f. A "Delete completed." message will appear once the file has been successfully deleted.
Also the game may lag for a few moments upon entering a new larger zoneas it will need to cache.
Please let us know if you require further assistance.
Best regards,
Chris Z.
Just so you have an accurate count I too among many others are having the issue of significant lag and slowdown once my save file was over 6 MB Any by significant I mean practicaly unplayable
