I never got around to filling it. Already at about 1.2TB fill, it was dead slow, and for that the 8GB RAM should suffice.

AFAIK, L2ARC will just "add more, slower RAM"...

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av idiomer med fremmed opprinnelse. I de fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
