i found the real problem, it was not the xl driver, but the geom mirror..
if i try to write to an other disk, not in the main systems raid1, then
download is ok, 10M/s...
then i tried to remove one disk from the raid1, and write on it..
the download is OK again...
when i sync the raid array it gives poor performance again 1M/s..
