As a SysAdmin, I'm always interested in any speedups to filesystem ops, since I tend to do lots of trawling through filesystems with find looking for data on filesystem usage, largest files, etc. So this is good news. Any numbers of how much better this is? I'm travelling tomorrow, so I won't have time to spin up a VM and play, though it's tempting to do so.
Thanks, John
