screen. Once it has done the screen draw and the path is established,
Where is the raid10 located and how is it interfaced to the device
you're accessing it from? That delay, along with other things you
mentioned suggests (but this is only a guess without other relevant
information) a DNS timeout.
It is a separate 6 port sata controller because the mobo is out of
ports. There is no obvious lag during bios post or grub booting it.

A dhcpd has been installed, but is limited to issuing a single fixed
address to a 3d printer plugged into my network, as the printer doesn't
seem to know what to do with a hosts file that runs the rest of my home
network. Anything else you want, just ask.
Cheers,
