SLOW Slow slow...
I am trying to back up my dns323 to a local hard drives so that I can update the firmware but it is going oh so slow.
In 24 hours it has only copied 90Gb. (about 1MB/s) am I expecting to much or will it really take 14 whole days to complete copying my 1.2TB of data?
All drives (DNS and local) are a 750GB Seagate 7200 Barracuda's. Networks are both GBit to the same Gbit switch.
I have the DNS mapped to N: and M: and using xcopy to move the files. My desktop has on access virus scans turned off and shows CPU utilization <2% Network Utilization <1%. A small test with windows drag and drop copy seemed just as slow.
Anyone have a clue how to speed this thing up?
Thanks,
Dave.

Re: SLOW Slow slow...
I get ~15MBytes/sec read/write to my DNS-323 from a winXP machine, so 1MByte/s is really
slow. You could start by trying another computer to access the DNS-323. If the other computer
is any faster, that might isolate the problem to your local system. If the other computer is just
as slow this could point to a general network problem or problem with the DNS-323.
General troubleshooting issues:
Is the DNS-323 using DHCP or static address? - make it static
Are both DSN-323 and local system have the same workgroup? - same workgroup
Are you mapping by IP address or name? - map by IP address
If all else fails, you can always connect the drives from your DNS-323 directly to your local system
(assuming you are using winXP and have a SATA controller) with the ext2 file system driver for
windows http://www.fs-driver.org
DNS-323 • 2x Seagate Barracuda ES 7200.10 ST3250620NS 250GB SATAII (3.0Gb/s) 7200RPM 16MB • RAID1 • FW1.03 • ext2

Re: SLOW Slow slow...
OK after more tests this does not look like a DNS fault. Copying from the DNS to my other machine is about 10x faster and drives the ethernet up to about 14% vs the 1% on my main machine. Also copying from the second to main machine (no DNS involved) is about as fast as from the DNS.
Upshot is it looks like it is my main machine that has the problem but what?
There is no virus software running.
I did conclude that any single process seems to be limited to 1% network utilization.
With one copy (from DNS Vol 1) network utilization 1%
Start a second copy from my second machine net utilization climbs to 2%
Start a third copy (from DNS Vol2) net utilization rises to 3%
Anyone got an idea what could cause this?
Thanks,
Dave.

Re: SLOW Slow slow...
What OS does the slow machine run?
And the fast one?
What speeds do you get between the slow machine direct to the fast one?
Have you made any changes to the network settings like mtu sizes or jumbo frames?

Re: SLOW Slow slow...
Two areas you could explore -
Fragmentation - when last did you defrag the disks in that system?
NIC drivers - I've seen pretty dismal performance with some Realtek based 1GB NICs if used with the MS driver, you need to use the driver supplied with the NIC to get acceptable performance.

Re: SLOW Slow slow...
Well, this morning I think I fixed the problem.
The machine is running XP Pro with NVidia on board Nic.
To Fix I went to the Device Manager and deleted the Nic, this also asked to delete the NVidia software (which I did).
When I rebooted XP added the NIC back in and all was good. I now use 12% on my GB Nic with a single copy.

Re: SLOW Slow slow...
It fixed my similar problem too. Running XP Pro on a Lenovo T61p.
I had upload rates around 0.4 to 0.5 MB/s and have been struggling
for quite a while!
I was just about to give up when I saw your post...
Removed the device, booted, it found new hardware, tried NAS tester -> 9 MB/s both ways...
Thanks David, you saved my day 
Cheers,
Peter
