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 :)

- I'm wondering, is CIFS that slow, or do i have a misconfiguration ?
Tonight, i was transfering files with ftp while sabnzbd was DLing at full speed (2MB/s), the speed was 100+ MB/s. And on the other hand, i can't seen to exceed 50-60MB/s with CIFS. - I am definitely seeing a very large difference in write speed between the cache and the disks. When I initiate a write I get 800+ Mbit/sec for about 700MB of data, and then a halt while the NAS writes to disk, then a very consistent pattern of around 100Mbit/sec for 200MB of data and then halt as the NAS writes it, repeat, until the data is all sent. If I send less than 700MB, then it is like lightning, but once the cache is full my writes are much slower.
H. - The problem seems to lie with your HDDs :/
What models ? What does the SMART say about them ? You could also install bonnie add-on and see what you get. - Mine? I have 6x Seagate Constellation ST32000644NS drives. No problems in SMART listed. I have Bonnie installed but it was unreliable so I disabled it.
H. - I take it back - it was the ntop addin that sucked.

H. - Ugh, that didn't format well.

Wrapping with a CODE block helps a bit.glashoppah wrote: Ugh, that didn't format well. - Well, as i see (i've formatted it with excel), your benchmark clearly shows a problem with sequential outpout. It shows 15.9MB/s, with 2% CPU load (and 37000ms latency), while mine reaches 100MB/s (and my ultra4 is crealy slower than your Pro6).
- Odd - first of all I don't have any problems reading *from* the ReadyNAS, it seems to be able to put data on the wire just fine. And my Mac has a lot of RAM and a hardware controller and apparently a great caching strategy, so it can take whatever the NAS dishes out. I get data out of the ReadyNAS at very consistent and high rates.
It's writing *to* the ReadyNAS that is slow and choppy and clearly governed by drive performance and caching.
Regarding the issue you note - any ideas? This device is configured relatively "out-of-the-box" except for the double-redundancy config of XRAID-2. I've had more than one of these and have had 500G, 1T and 2T drives in them, all enterprise-class Seagate Constellations.
