I would neither thinkg about the first one.
Maybe there's some CPU limit in testers' system.

many filesystems work bad when there's too much of directory entries.
smaller values should help. the number_of_files/(l1*l2) should not be bigger
than any of l1 and l2. With default values (16 256) you should not have
more than 1 million (~ 16*256*256) of entries. For more, increase L1...
