Post your performance results

Hi

i am condsidering purchasing a Infrant ReadyNAS NV+ 256MB - 1TB (Fitted with Four 250GB Seagate Enterprise Series SATA Disks), we had transfer speed problems with a LaCie Ethernet Disk RAID so i need to know that transfer speeds will be good on a ReadyNAS NV+. so i ran the iometer test on my machine to see if we would get good transfer speeds in our gigabit network, now im not too sure if im looking at the correct figures, so could someone please confirm that i am.

on my excel results spreadsheet it says 9.662824 in the MBps column for the write test and 7.783678 in the MBps column for the read test. i am using a dell inspiron 9400 laptop, 1gb ram, 1.66ghz. i ran the test on my internal drive.

would the results still be accurate if the test is ran on my internal drive or do i need to run on a different drive??

thanks

kamesh, please open a new thread. This thread is reserved for folks running IOMeter with the ReadyNAS.

Here are my IOMeter results, both before and after I upgraded my ReadyNas NV SODIMM.

System:
Intel QX6700 on nVidia nForce 680i MB with gigabit LAN, jumbo frames set at 4500, running WinXP Pro
SMC GS8 Gigabit switch
ReadyNas NV running Radiator 3.01c1-p6 in XRAID
4x Maxtor 300GB 7V300F0 drives (yes, I know Maxtors have been a problem for ReadyNAS, but these seem ok)
Disk write cache: ENABLED
Journaling: ALL DISABLED
Fast CIFS Writes: ON
Force CIFS filename case-sensitivity: ON
All wired with Cat6 cabling

With original SODIMM, IO-Meter shows:
Reads: 23.1 MB/sec
Writes: 8.2 MB/sec

I think my slow writes are due to heavy volume fragmentation. I have had better write performance when I first started using the NV, but now that it's 70% full, writes have degraded in performance.

After installing the Patriot SODIMM, the welcome page of the NV showed Memory: 1024 MB 2-2-2-6. IO-Meter benchmarks now show:

Patriot SODIMM:
Reads: 20.9 MB/sec
Writes: 7.8 MB/sec

Any thoughts as to the performance hit after upgrading to 1GB RAM?

--- [ edit ] ---
played around with jumo frames, and found that I got better performance after turning it off in both my PC's NIC and on the NV.

Jumbo Frames ON:
Reads: 25.1 MB/s
Writes: 7.4 MB/s

Jumbo Frames OFF:
Reads: 25.9 MB/s
Writes: 20.0 MB/s

weirder and weirder.

Here are my results using the IOMeter supplied configuration with the following setup:

Worker: XP Pro SP2, Athlon FX 60, ASUS A8N32-SLI, NVIDIA GigE LAN, 2GB RAM, Seagate 40GB ATAPI drive

Network: Netgear GS608 Gigabit Hub

Ready NAS NV+
RAIDiator™ v3.01c1-p6

Slimserver streaming off
iTunes streaming on
UPnP streaming off
Speed: Auto-Negotiated
MTU: 1500

Read: 15.2 MBps
Write: 14.9 MBps

I'm having some errors with the GigE/Jumbo Frames setup, so I'll have to figure that out before posting those numbers.

Laptop with Intel Core Duo T2400 with 2GB of Ram and onboard GB nic, with a Dlink gigabit router DI-724GU or direct connection [laptop <easynas>this makes NO difference!)

Results:
Read: 18 MB/sec
Write: 9 MB/sec

For an EasynNAS nv+ in a gigabit ethernet this is not blazing fast! A lot of people are getting way better results here!

I checked/tried :

- The EasyNAS front-end was not running when testing.
- The new and short cat 5e cable was provided to me by Dlink so it must be optimal!
- i'm using the lastest Vista-compatible drivers for my network card
- i'm not using a UPS
- i disabled my trend micro virus scanner
- i enabled 'jumbo frames' in Vista and on the EasyNAS but this made things worse or didn't change anything (can't remember) but certainly no improvement!
- tried the two add-ons (vistaboost and oplocks), together and seperately but this made things worse or no improvement (can't remember)
- tried disabling journaling completely but no improvement whatsoever!

i'm running out of ideas.... anyone?

thanks

A couple of thoughts ...

1. Could check the NV+ Network tab and see if there are any network errors (just to help rule that out). I think someone once said that > 100 unrecovered TCP retransmits in 24 hrs was bad.

2. As I recall, they may have removed this option in the p6 firmware, but check the Performance tab and see if you can check "Force CIFS filename case-sensitivity" ... I found this made a big difference for me.

3. What hard drives are in the unit? Have you checked the Health tab and their SMART status? Are there unusually high error counts?

1. Sorry, i looked and i looked but i can't find it. Where are the network errors located?

2. You're right, it's been removed in the last firmware version.

3. Oh oh... maybe bad news here... the drives have a green led, but when i click the Smart link is can see with all three:

Start Stop Count 2
Seek Error Rate 3983913
Power On Hours 91
Power Cycle Count 4
Hardware ECC Recovered 196278575

The Seek Error Rate varies with all 3 drives but is around this number more or less. All the other values are 0.
Is this bad? THe drives are new and are installed by the dealer.


thanks for the help!

I have an NV, not an NV+, but I'm assuming the web GUI is similar. If you go to the Network tab on the left, then Ethernet, then on the page that loads click the "show errors" button on the page, you'll get a pop-up window that lists your network errors.

Regarding your SMART errors, take a look at:
http://www.infrant.com/wiki/index.php/F ... ld_I_do.3F

If the drives the dealer installed are Seagate drives, then that could explain your falsely high error rates. Read the Wiki, and open your NAS up to check what model drive was installed, then check the hardware compability list to make sure the drive is on there.

A dump of my results as I went (quite approximate numbers - I was copying a 100MB file back and forth):

over DLINK DIR 655 wireless router/gigabit switch
(ReadyNAS Jumbo frames ON)

Mac AFP
read 22MBs
write 4MBs

Mac SMB
read 13MBs
write 10MBs


direct connect between Mac and NAS
Mac AFP
30MBs read
5MBs write

not a huge improvement compared to passing through the router/switch

Mac SMB
11MBs read
9MBs write



Mac Jumbo frames ON, still direct connect
[To enable jumbo gigabit Ethernet frames on the iMac (up to 9000 bytes), you have to select the "jumbo" maximum packet size in System Preferences:Network:Built-in Ethernet:Ethernet. There is an outdated Apple article explaining which devices supported jumbo frames as of the date of the article (4/22/04):
http://docs.info.apple.com/article.html?artnum=107962]

AFP
read 25MBs
write 30MBs
serious write boost!

SMB
read 11MBs
write 15MBs
not much better


Mac and NAS Jumbo Frames ON, this time through dlink DIR655
AFP (forget SMB)
read 25MBs
write 5MBs
uh-oh, back to square 1

Jumbo frames OFF on Mac AND NAS
AFP
read 25MBs
write 20MBs
ah-ha - back to 'high' write speeds


The DIR655 clearly does not do good with Jumbo frames. Best to set everything back to MTU 1500 in System Preferences:Network:Built-in Ethernet:Ethernet, AND (very importantly) switch off Jumbo on the NAS, too. Use AFP, not SMB of NFS.

I'm getting myself a SMC_8508T switch to cope with the Jumbo frames, and CAT6 cables to replace my existing CAT5 cables.

Still, I'm not too impressed with the speeds - I want to get to the highs I see on this thread (50MBs). The direct connection with Jumbo frames ON is pretty much the max performance I can expect from my NAS connected to my Mac. Or am I wrong? Anyone know how to boost my performance further? Maybe tune the MTU on the mac to about 7000 instead of 9000, to match the NAS speed better? I'll try that when I get my new switch.
