Reiser4 works fine with 100M entries in a directory, so VFS is not a
bottleneck here.


how about with ftp running on top? Try running FTP in directory with
100M entries. See how long it takes to return the data to
the remote client for a dir listing.

What filesystem are you using?  If it's ext3 without dirindex turned
on, that would definitely explain it.

Thanks. I'll enable dirindex.
