If you do not restart the thin client, the changes made will not be saved until the thin client is restarted.

• Amount of RAM to be used for FBWF Cache - Shows (in MB) the amount of RAM (in MB) that is to be used as File Based Write Filter cache. The value is calculated based on the following formula: Amount of RAM to be used for FBWF Cache = Total Available Physical RAM multiplied by the Percentage of RAM to be used.
• Warning #1 (%) - Shows the FBWF cache percentage value at which a Low Memory warning message will be displayed to the user (Default value = 85, Minimum value = 50, Maximum value = 90).
• Warning #2 (%) - Shows the FBWF cache percentage value at which a Critical Memory warning message will be displayed to the user, along with another message display counting down the number of seconds before automatic rebooting will occur (Default value = 95, Minimum value = 55, Maximum value = 95).
• Reboot Time Delay (in seconds) - Shows the number of seconds that will lapse before system reboot in the Warning #2 (%) case of cache overflow.
• Advanced Cache Settings area includes options to allow you to improve the effectiveness of cache memory (Cache Compression, Cache
