Hi, I have HP NetServer LH 3000 machine with the NetRAID controller ... the dmesg says: amr0: <LSILogic MegaRAID> mem 0xe0000000-0xefffffff irq 5 at device 3.1 on pci3 amr0: <Integrated HP NetRAID (T7)> Firmware E.01.00, BIOS B.02.01, 32MB RAM There is 1 disk (system) alone (RAID 0) and 3 disks (data) configured as RAID 5 array. The problem is that the write performance is very poor - about 6 - 10 times slower than the read performance (with softupdates on). Any idea what can be wrong would be really welcome. Thanks Mira P.S. Unfortunately I'm currently loosing the battle with other (W2K based) servers in hearts of my users in the office. Just because o that problem.
