The settings storage can be used to store and retrieve various

configurable parameters. This storage is a RAM-based map (for fast access)

reboots).

If enabled saving to the storages will be cached.
|

|
|
|
||
|
|
Whenever a save is triggered, the settings will only
|
||
|
|
be saved in the RAM map (and will be immediately
|
||
|
|
effective). Writes to the storages though will
|
||
|
|
happen after a small delay.
|
||
|
|
|
||
|
|
This improves performance greatly when multiple
|
||
|
|
successive saves are to be performed, as the actual
|
||
|
|
write will happen only once, asynchronously.
