Ill hope this help your guy's for the flashplayer cache problems
This way you can clear the cache once a day or two
After changing the settings to 1mb or 100kb it seems that facebook also performing faster with the app topeleven (faster loading)
Update: Update your network drivers from pc and the video-drivers
