dumpe2fs reports that dir_index option is enabled. But thank you for
the suggestion.

Hi all,
I plan on having about 100M files totaling about 8.5TiBytes. To see
how ext3 would perform with large numbers of files I've written a test
program which creates a configurable number of files into a configurable
number of directories, reads from those files, lists them and then
deletes them. Even up to 1M files ext3 seems to perform well and scale
linearly; the time to execute the program on 1M files is about double
the time it takes it to execute on .5M files. But past 1M files it
seems to have n^2 scalability. Test details appear below.
Looking at the various options for ext3 nothing jumps out as the obvious
one to use to improve performance.
Any recommendations?
Did you make sure directory indexing is available? I think that is the
default now for ext3, but maybe it wasn't turned on for your test.
