Post your performance results

[michelkenny]

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

Great idea. You've been stickied

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...

ReasyNAS NV with single 750GB drive. UPS, journaling off, cache on, etc.

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?

[michelkenny]

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.

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.
