After updating my servers from NW6.5 SP5 to SP7, I have getting a decreasing performance on disk access.

We use loads of small (below 1MB) word, excel, C5 (accounting application) and backups are generally 90% longer to complete.

Backup speed prior to Sp7: 921,9MB/min
Backup speed after SP7: 467,5MB/min

Server information:

System: NW 6.5 SP7
HW: HP Proliant ML350 G3
Ram: 2GB

Services running: DHCP
Main focus: File sharing
Raid: Raid 5

Nothing was changed but the SP upgrade.
