We have a few NW6.5SP5 servers. One is an iSCSI-target for a
"fileserver" and a GroupWise server. The DATA/GroupWise partitions of
these servers are mirrored to the iSCSI server.
If I copy files on the console or over the network, the speed in NRM is
always around the 6MB/s. If the mirror is restarted, due to a broken
link or something, the speed is around 20MB/s.

Where can I find the difference? Is this the difference between a NSS
and an iSCSI partition?
