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 :)

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 btv wrote: Hi,

16MB/s over 100mbit ethernet? I think there's some caching behavior at work...
-brendan- ReasyNAS NV with single 750GB drive. UPS, journaling off, cache on, etc.
Netgear 100mbit router/switch
PC: Nvidia motherboard/gigabit NIC, 1 GB RAM, Athlon
Read: 8.3 MB/sec
Write: 9.5 MB/sec - 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? - 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.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.

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.patja wrote: 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.

I believe that's sector count, so you may even want to double that size.yoh-dah wrote: patja wrote: 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.

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.
