Post your performance results

I thought it might be interesting to see what kind of performance everyone is getting with IO Meter so that we can compare what we're getting. So I thought we could all post our results in this thread for easy comparison.

You can run IO Meter by following the steps here: http://www.infrant.com/forum/viewtopic.php?t=265

Please post your hardware specs, other relevant info, and IO Meter results. Maybe this could get stickied? Or ignored if no one cares 🙂

Here's my info:

2 gigs ram
Seagate ST3250824AS 250gb Hard Disk
Windows Vista x86 RC1 (if that makes a difference)

Dell PowerConnect 2708 Gigabit switch (no jumbo frames)
Cat 6 cabling

Ps. All utp cables are brand new
Ps. All utp cables are not lying besides electrical cables, this would also slow down speed a lot

16MB/s over 100mbit ethernet? I think there's some caching behavior at work...

Perf results

I am seeing some pretty strong results...makes me wonder if I missed something in the Iometer setup instructions, but I've triple checked them. I've done 6 runs now and see:

Writes: 35 or 56 MBps (half the time it is 35, half 56)
Reads: 33, 47, and 72 MBps (of my 6 runs I've got two at each of these)

Everything on the ReadyNAS is setup per the instructions on the forum. I am only sharing as CIFS. No SMB and no HTTP.

The network switch is a SMCGS8

My PC is an ASUS A8N-E, Athlon X2 3800+, 2 GB RAM, onboard gig ethernet (Nvidia)

Do you guys see consistent results from one run to the next?

Re: Post your performance results

Yes my results are always pretty much the same for multiple runs. In the thread where it explains how to use IO Meter, I think there's a file that you can download that has all the right settings for a test. All you have to do is pick the drive you have mapped.

As much as I'd like to want to believe the ReadyNAS is that fast, I think it might have to do more with caching on the PC side as you have 2GB of memory. If you use a larger test data size with IOMeter, you'll probably get a more consistent result.

That makes sense. I increased the maximum disk size to 4096000 and am now getting reads of 47 MBps and writes of 42 MBps pretty consistently.

I believe that's sector count, so you may even want to double that size.

I doubled it to 8192000 and am seeing writes at 53 - 55 and reads consistently at 47. I am using the iometer.icf file posted on the Iometer thread, just changing the target to my mapped drive and increasing the max disk size sectors.

I guess we'll need to confiscate your PC for our benchmark lab 😎 Actually other test you can do is to drag & drop a large file, i.e. 4GB or larger, and time that.

Re: Post your performance results

My results running RAIDiator™ v3.00c1-p2 [1.00a025] from a 3.2Ghz Athlon 64 PC with 1GB RAM via gigabit connection on a Netgear GS108 switch to my ReadyNAS NV.

4 x WDC WD2000JS 200GB drives in X-Raid.

Settings (all standard I believe):

Enable disk write cache: Enabled
Disable full data journaling: Enabled
Disable journaling: Disabled
Enable jumbo frames: Disabled
Optimise for OS X: Disabled
Enable fast CIFS writes: Enabled
Enable fast USB disk writes: Disabled

Network shows 0 errors.

Write MBps = 15.71
Read MBps = 25.03

I've previously run tests with direct connection with similar results, and jumbo frames enabled (at both ends) with a reduction in results.

Personally I think it does the job and looks great, but I would expect better throughput (how can read performance over four drives give worse performance than native read performance of a single drive? I understand there is a write penalty with Raid 5).

Network stack and file protocol overhead?

These speeds are extremely quick! Gb speed caps at 125MB/sec assuming everything is perfect. And we all know that it is never perfect.

When I get everything setup I'll have a Linksys SRW2008 switch which has a 16Gb non-blocking backplane so this won't be the bottleneck. I have an Asus A8V motherboard with a Marvell Gb nic. I have an AMD 3500+ and 2GB Memory. If I don't get good throughput, I may upgrade my NIC. I bought 2 Seagate 250GB ES drives to go with my NV.

Re: Post your performance results

I did some performance tests last night.

Specs:
ReadynasNV - 256MB w/ 2 Seagate ES 250GB drives
PC Asus A8V - AMD 3500+ with 2GB Memory
PC NIC - Yukon Marvell 10/100/1000 (supports jumbo frames)


With a Linksys WRT54G and everything connected at 100/full I get:

Read: 9.28MB/s
Write: 8.54MB/s


With my new Linksys SRW2008(8 port Gb switch w/ full 16Gb backplane non-blocking - supports jumbo frames) and everything connnected at 1000/full)

Read: 29.x MB/s
Write: 18.x MB/s

I tried to enable jumbo frames on my NIC, the NV and the switch bbut something went wrong so I have no results with jumbo frames enabled. I hope to have that issue resolved soon and I will post back here.

Added 10/12/2006:

I fnally got jumbo frames working and my write scores improved dramatically, but my read scores dropped a tad.

With Jumbo Frames enabled on my PC, switch and NV:

Read: 27.52
Write: 23.75

Dreadful.

Read: 15.32
Write: 16.02

OK, so I increase my switch 10x, but my performance goes up a meagre 50%? I understand that jumbo frames will help write, but read is in the toilet... it is operating at a theoretical 122 MBit -- not 1000 MBit.

Note, this is after rebooting and disabling Antivirus, and every program and service running. Before this "clean reboot:"
Read: 14.68

(so, my NAV, with Outlook replicating every minute, my read was only 0.64 mbit worse)

Yeah, I may try a direct connection cable, but at this point, I am vastly disappointed; I expect better than 0.12 GBit performance out of a gigabit device... I may try a separate GBit NIC, but my "as-is" PC can natively do better with other GBit personal computers on a gbit network...


Definitely you should eliminate the switch first with direct connect. Most likely it is something like auto negotation failed. I highly recommend to manually set your speed/duplex on each device. This is a very common and overlooked problem.

Re: Post your performance results

Did you set the speed/duplex on the PC, NAS, and Switch? You must set it manually on all 3. Also, please list your specs of your PC. Do you see any errors on the Network/Ethernet screen when you click "show errors"? If so, post them here.

Re: Post your performance results

Well crap, I just realized the NV doesn't have the option to manually set 1000Mb. I have 10 or 100/half & 10 or 100/full and then auto negotiation. So forget what I said about manually setting speed/duplex on the NV. I just found out my nic card is the same way, yet my switch can do it.
