After upgrading a GroupWise server from NW6SP5 to NW 6.5SP6, the backup speed to is only 500K/min according to TSATEST. After the upgrade IP would not bind to the board (Intel Pro/100 S) until I changed the Max Physical Receive Packet Size to 2048. I see that other servers are set to 4224 so I bumped the GW server up, which did not help. Other server speed is 300MB/min. I'm going through TID 3341011.
