Cheers, that 64 bytes is interesting. Do you get a perf benefit on access to the file, too? Is it affected by long filenames at all?

Also worthy of note, to date there is no way to modify the block size. It's hardcoded in wafl.

While we're on the subject of WAFL trivia, WAFL does not split a 4K block into fragments, so files always consume disk space in even multiples of 4K bytes.
However, if the length of a file is 64 bytes or less, then the file data is stored in the inode and no data blocks are consumed. WAFL uses the space in the inode that otherwise holds the data block list.
This is nice because most symbolic links are small enough to fit in the inode.
