It takes noticably longer to ssh into the machine also in the single-threaded case (using dd to write to the device), but the system remains usable. When the rsync job is running, it becomes unusable quickly.
However, reducing the queue depth with
echo 16 > /sys/block/sda/device/queue_depth
as suggested by Adam, solves all problems.
Thanks all for your help. Andre -- The only person who always got his work done by Friday was Robinson Crusoe [unhandled content-type:application/pgp-signature] | |
