Hi Christoph, hi list,
I don;t have ONE dir with that 11 million files, it's one dir with many
directories and a total of about 11 million files AND dirs! See output

It didn't improve, 100 min again.

rm took about 110 min.

No, I did not use it, but I was thinking about and ran the script from
http://sandeen.net/misc/summarise_stat.pl and got as an example on /bin:
# /net/c3m/usr/local/software/XFS/summarise_stat.pl /bin/
9 6.2% are scripts (shell, perl, whatever)
65 44.8% don't use any stat() family calls at all
61 42.1% use 32-bit stat() family interfaces only
9 6.2% use 64-bit stat64() family interfaces only
1 0.7% use both 32-bit and 64-bit stat() family interfaces
So I was not sure if I should use inode64 or not.
This are the times that the run took yesterday:
