Not really, but it turned into one. The camera I was using had the ability (rather handily) to upload a still image once per second via FTP to a server of my choosing. It didn't have the ability to organize them for me in a neat directory hierarchy. So on holidays I went for 3 weeks and came back to ~2M images in the same directory. > This is the 2nd or 3rd mail in recent months from people saying "I > decided to do something utterly stupid with my filesystem[1] and now I'm > asking why performance sucks". > > Why can people not create proper directory tree layouts to avoid this > problem regardless of what filesystem is used? I just don't get it. I'm not sure it's utterly stupid; I didn't expect legendarily fast performance from 'ls' or anything else that enumerated the contents of the directory when all the files were there. Now that the files are neatly organized, I expected fstatfs() on the directory to become fast again. It isn't. I'd like to understand why (or maybe learn a new trick or two about inspecting ZFS...)
