I have found and dev this point into the ultracopier's wiki. It's the algo the problem. But I don't know if the problem remain at this time.
Mostly:
- Simple loop have mutualy slow down of read and write
- close() sync the file to the FS and have big slow down with lot of small file
- open() close() is better with concurrency but data transfer not

I close the bug due to old (now the new kernel, ext4, ... all have changed)
