i tried to copy a groupwise postoffice from one NW6.5 server to another, which has been very slow. With xcopy (like mentioned in TID10052948) it took more than 2 hours to copy about 10GB. Using toolbox.nlm to copy directly from server to server, the result was not better. Copying from or to a Windows client seems to be quicker (but not perfect). The source server is able to backup this postoffice with 45GB to tape within 75 minutes, so it should not be a disk problem.
Both servers are connected to one GBit Switch, full duplex, no other traffic while copying.
How to speed up this process?
