I have one of these (ReadyNAS Duo) configured with RAID1 and 2 x 1TB HDD's. My current problem is a lack of performance. I have two NFS mounts from one machine, one if my very old NFS server (PC running linux with IDE HDD's installed) which gets this result: host:/mnt# dd if=/dev/zero of=/tmp/test bs=1024 count=102400 102400+0 records in 102400+0 records out 104857600 bytes (105 MB) copied, 2.74108 s, 38.3 MB/s Meanwhile the same test with the netgear gets this: host:/mnt# dd if=/dev/zero of=nas/media/test bs=1024 count=102400 102400+0 records in 102400+0 records out 104857600 bytes (105 MB) copied, 125.684 s, 834 kB/s The test machine is connected via gigabit to the switch, and the netgear + old NFS are both also connected to the same switch. The maximum performance I've seen with the netgear is around 2.5MB/s, but with samba I've seen around 25MB/s so I'd love to know why I lose 10 times the performance! Any hints/tips on improving the performance would be greatly appreciated...
