> I have 100+TB datasets and with a large enough SSD/RAM for L1/L2 arc ZFS edges out.

and your claim is that you tested it against btrfs on the same workload? Maybe you could post some specific numbers from running command from this thread? https://www.reddit.com/r/zfs/comments/1i3yjpt/very_poor_perf...

> Hell even the compression algorithm that ZFS has uses/has access to (LZ4) is faster than what btrfs uses and with enough IO that matters.

lz4 compression rate was 2x vs 7x for zstd on my data (bunch of numbers), so I didn't see point of uzing lz4 compression at all because benefits are not large enough.
