F4-210: CPU utilisation copying files

[phirephoto]

Hi,

F4-210, latest firmware.

Whenever I copy a decent number of files (or any large file) - or basically any file operation that takes longer than say a minute or two, I get:

Security Consultant

CPU utilisation has exceeded 90%! Please check if there is a process running abnormally in your control panel.

Is this normal?

This is normal, as F4-210 has lower processing performance and is prone to high CPU usage. If you find it annoying, you can ignore it or turn off the relevant prompts in the settings.
