What’s the topology of your array? How many disks? L2ARC doesn't help with that much ram because your main memory will be faster than even mirrored nvme caches

- sneak 7y ago8x 10TB HDD, 4x 512TB flash, all 6gpbs SATA. 256GB ram, 40 cores. The HDDs are all in raidz2, with the SSDs all as L2ARC. I have an ubuntu mirror on the machine that's around 150gb, and doing a `tar -c $MIRRORPATH | pv > /dev/null` shows lots of reads from the HDDs, even on second, third, fourth runs. It confuses me.
