Post your performance results

I'll see if I can buy a CAT6 cable tomorrow

I learned a lot from the forum and I would like to help other people as well.
I have been frustrated on the performance of my NV+ for a long time (transferring 4.5GB file from windows to NAS at 7MB/s) and finally I took some serious time and money to find out why.

NV+ w/ 1GB RAM and use default XRAID and 4 2TB seagate LP drive with 32MB cache on HCL.

Here is what I did for troubleshooting:
replaced switch from Trendnet green gigabit switch to Cisco SG200-8. I checked the cisco switch web gui and there is no error on both ports to the NAS and windows PC.
Same slow 7MB/sec transfer

replaced cables from cat 5e to cat 6, verify cisco switch no error on both ports.
same slow 7MB/sec transfer

One of IT guy I work with told me to try update the NIC driver to the latest.
Since I am using onboard NIC, so I checked with Asus web site and it showed that I am using their latest NIC driver, but looking at the date, they haven't come out a new driver for a long time. I went ahead and found out the chip of the NIC (realtek) and download the latest driver from realtek website. I installed the drivers and test it again.

the result: ~22MB/sec

try to download and install the latest NIC driver for your PC from the chip manufacture instead of the motherboard manufacture !

After some frustration with a new Ultra 4 (populated with 4 x HITACHI Deskstar 7K2000 HDS722020ALA330 (0F10311) 2TB 7200 RPM drives in X-RAID2) getting a paltry 6-7 MBps read speed from a newly built Windows 7 64-bit rig, I did some research and found I could run jumbo frames on my Trendnet router (TEW-633GR). Before that I tried TCP Optimizer (ended up resetting to Windows defaults), then using the Vista/Win7 tweaks from SpeedGuide.net (kept most of those), disabled flow control on the Realtek 8111E onboard NIC (briefly got 100 MBps on a large transfer! ... but it didn't hold after a reboot :( reset it to Enabled, as there were a lot of network errors produced, even though the copied file, copied back, passed a checksum matching test with the original file) ... I finally got smart and updated the Realtek's driver and enabled jumbo frames on all NICs attached to the HP Procurve 1800-8 G switch, enabling switch-wide JFs on that.

I then did a drag-and-drop copy test of a 9 GB file from the Ultra 4 to the Western Digital Caviar Black WD1002FAEX 1TB 7200 RPM SATA 3 system drive.... over 100 MBps!!! :shock: I was stunned. Repeated that test several times after a few reboots. Pure gold. A driver update + JFs enabled on an old D-Link DGE-530T on an XP Pro SP3 box also resulted in increased read speeds from the Ultra 4 (in the low 30s MBps). Similarly my original Infrant (remember THEM!!! ;-) ) ReadyNAS (Sparc-powered 256 MB of RAM little beast :-) ) also benefited from JFs being enabled. But the Ultra 4 + new Win 7 rig combo was my main concern.

I was really worried about that nice Procurve switch, but it's a rock, so I wasn't willing to throw it under the bus.

As far as the Vista/Win7 tweakable parameters go, you just gotta play with them, but the SpeedGuide.net page is a gem.

re: IOMeter, I messed around with it a bit on the XP box, but for my purposes the practical drag-and-drop tests were sufficient indicators that the problem had been well and truly licked. I'd be happy to drag IOMeter out and run it on both PCs and post results, but someone smarter than me is going to have to tell me how to get meaningful results. For example, after opening the .icf file provided by Infr-- errrrr, Netgear, and running the tests, there was nothing listed for Read Speed in MBps. The Write test seemed to indicate 44/45 MBps, and that seems about right. Didn't have time to mess around with it further.

Anyway, hope these anecdotal data will help someone or provide encouragement to tinker.

Cheers.

I should add that this is with CIFS and HTTP/S the only enabled services, and that the Ultra 4 and the original ReadyNAS are running the current RAIDiators for each model.

i'm a new user of readynas products. Mistakenly bought the nv+, however I decided to do some damage control and optimize the nas as much as possible. Spent 3 days researching these forums and others. The results are as follows:

Real-life speed figures:

write: 27 - 30 MB/s
read: 33 - 35 MB/s

IOMETER test (never seen such figures on a sustained basis in real-life):
write: 33.6 MBps
read: 38.59 MBps

Using:

CIFS
Realtek onboard nic, 7K Jumbo frames on, latest drivers
cat 6 cables
tplink 1043 router
windows 7 with LM2 fix
4.1.7, minimal services enabled

working good.thanx

Hi,

my performance results :

Read 75-92 MB/s
Write 60-75 MB/s

Im uising 6 x WD 2TB WDEARX

JumboFrames activated / Windows 7

Im really happy with my ReadyNas Ultra 6 :-)

ReadyNAS NV+, (4xST2000VX002-1AH166, Seagate SV35) "upgraded" with 1GB ram. Gigabit network crossing a DELL PowerConnect 2724, and a D-link DGS-1008D. Using CAT5 cable, FTP. System running the test is a C2D E8400 on a Gigabyte EP45-DS4, 4GB memory.
I went with LAN Speed Test, 2GB test size, and got 57.9396744 Mbps writes, and 76.1343002 reads.
IOmeter provides a test result i'm not sure how to look at, it says 11.82 MBs per Second. 256K write, 2048000 sectors. (Ends up being a 1GB testfile)

It's not like the results match, so to speak.
B!

Hi

I would love some help here please. I am tired of the rubbish transfer speeds I'm seeing from my ReadyNAS, especially now I'm streaming music and video.

Surely I should be seeing better than the iometer results of 4.5MB/s read and 15MB/s write !!!

I have my PC (Lenovo R61) setup on my table next to the ReadyNAS NV+ with a new Netgear GS605AV in between and 1m Cat5e cables.

NAS has 4x 500GB discs (2 Seagate, 2 Samsung). 1GB RAM. Auto NIC, MTU 1500, No jumbo frames, only CIFS and HTTP enabled.
PC has latest(!) Vista, Intel GB NIC, 2GHz CPU, 3GB RAM.

I'm convinced the problem is with the ReadyNAS as even moving files between shares is painfully slow.

All advice welcome please!

Hi All,

My performance on the DUO with 2 samsung hd103UJ 931GB in X-Raid

drop files (4GB):
write: 19.2 MB/s
read: 34.3 MB/s

IOMETER test (3GB):
write: 25.6 MBs
read: 35.8 MBs

LAN Speed test v 1.1.7 (3GB):
write: 13.65 MB/s
read: 38.84 MB/s

Intel NAS Performance Toolkit:
write: 19.3 MB/s
read: 32.6 MB/s

Using:
CIFS
NVIDIA onboard nic, 7K Jumbo frames OFF, on both Duo and Nic! (gives better results)
cat 6 cables
windows 7
RAIDIATOR: 4.1.9-T2

I'm happy now with the results. I had to install the beta 4.1.9-T2 because 4.1.8 gives terrible results and also disabling the jumbo frames improved my results.

ReadyNAS Ultra 4 [X-RAID2]
RAIDiator 4.2.19
X-RAID2, 2 disks, 42% of 913 GB used
ch1: WDC WD10EARS-00Y5B1 [931 GB]
ch2: WDC WD10EARS-00Y5B1 [931 GB]

Test done from a 1st gen MacBook (core duo) over gigabit ethernet with jumbo frames enabled on both the NAS and the Mac (and verified to actually work). The mac is plugged into an 8 port gigabit netgear switch which then runs to a 4 port gigabit netgear (WNDR3700v2) which the ReadyNAS is plugged into.



I'm pretty happy with those #s and I'd assume I'll get better write speeds as I add more disks
