Ok, how's it scale on large filesystems? My manager was running some tests
this morning, 37TB f/s, and he said it seemed slow to respond. Also, dedup
seemed to take actual time - minutes. I saw him as he copied a 1G test
file to two or three other names, and it took time to go up, then level
off in size, with "size" being what we saw with df.
