You know, I don't know the answer to that. I would guess that it's the default compilation options, so if you say that it uses that by default, I'll believe you. I tried grepping the binary but didn't find anything that indicated type of structure. I found this in namei.c. Dunno if it helps: * Directory entry file type support and forward compatibility hooks * for B-tree directories by Theodore Ts'o (tytso@mit.edu), 1998 To me that doesn't really tell anything though. Anyway, I fired off an instance of my test program that created 3 million files and it finished in about 26 minutes. But then I found that I had filled the partition so I shortened the file size a little and restarted it. It was running when I left and I'll analyze the logs tomorrow. BTW, that was on a machine with 5400 RPM 40 GB HD and 128 Megs of RAM (trying to starve the system for resources to get rid of effects of caching and buffering). - -- Blue skies...
