General

Control Panel > Hardware & Power > General provides options to enable power recovery and Wake on LAN (WOL). You can also modify beep control, fan speed mode, and LED brightness here.

Memory Compression

You can enable Memory Compression to improve general system responsiveness under load by compressing the least recently used data in memory.

When you have multiple applications running and the memory begins to fill up, the dynamic Memory Compression shrinks the size of seldom-used items in memory, minimizing memory usage. When the items are needed again, they can be instantly uncompressed. This reduces the need to read and write memory swap files on disk, improving efficiency and responsiveness.

To enable Memory Compression, simply tick the checkbox.

Note:

Power Recovery

If the system shuts down due to unexpected power failure, the power recovery function allows the system to boot up automatically once power has been restored.

Wake on LAN

Enabling Wake on LAN (WOL) allows you to turn on your DiskStation over local area network or the Internet by entering the IP address (or DDNS hostname) and the MAC address of your DiskStation using a WOL application, such as Synology Assistant, DS finder or any other WOL applications.

Wake on LAN works only after the DiskStation is shut down properly by pressing the physical Power button or clicking Shutdown on the DSM interface. Keep the power cord plugged into a working power outlet after shutdown.
