Even withoyt skip_busy mode it will work much better.
The problem is on each file creation we start to look for a free block almost
from the beginning of disk. using no_unhashed_relocation mount option,
we make initial block allocation to be more random and cause less overhead
(verified).
And in this test we create a lot of 15k files.
Bye,
Oleg
