The zilstat tool is very helpful, thanks! I tried it on an X4500 NFS server, while extracting a 14MB tar archive, both via an NFS client, and locally on the X4500 itself. Over NFS, said extract took ~2 minutes, and showed peaks of 4MB/sec buffer-bytes going through the ZIL.
When run locally on the X4500, the extract took about 1 second, with zilstat showing all zeroes. I wonder if this is a case where that ZIL bypass kicks in for >32K writes, in the local tar extraction. Does zilstat's underlying dtrace include these bypass-writes in the totals it displays? I think if it's possible to get stats on this bypassed data, I'd like to see it as another column (or set of columns) in the zilstat output.
