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...
Hello all, I'd like some help/comments about my configuration, since I'm not seeing great performance.
I started a thread for comments in a separate thread, however I can't post the link due to forum policy for new users. The subject for the thread is: <b>Subpar Read Performance in 3 X 500MB Configuration</b>.
Test Rig:
IO Meter 2006
Xeon 5140 @ 2.33Ghz
4.00 GB Ram.
WD Raptor Drive
ReadNAS NV+ setup:
[X-RAID]
RAIDiator 4.00c1-p2 [1.00a037]
RAM: 1024 MB [2.5-3-3-7] (Patriot PC2700)
Volume C: Online, X-RAID (Expandable RAID), 3 disks, 0% of 907GB used
Raid Disks:
1. Seagate ST3500630NS [465 GB] (came with the unit)
2. Seagate ST3500630NS [465 GB] (came with the unit)
3. Seagate ST3500320NS [465 GB] (added on)
Full Data Journaling is disabled.
Using the IOmeter tests specified at the beginning of the thread I get the following:
Over 100Mbit Ether:
Read from NAS Server: 6.1 MB/sec
Write to NAS Server: 8.2 MB/sec
Compared to our Current Samba share:
Read from old server: 10.3 MB/Sec
Write to old server: 11.0 MB/Sec
If I do a direct connect between my machine and the NAS I can pull 1000Mbit (Jumbo frames off) with the following results...
Read from NAS Server: 12.7 MB/sec
Write to NAS Server: 16.9 MB/sec
So I'm fairly disappointed with the result, especially my read values off the NAS under 100Mbit. (The NAS will be put into production on a 100Mbit ether, so I'm not concerned with the GigEth performance).
I also ran the performance tests with journaling disabled, with similar results.
The Drive I added (the 320NS) has the SN04 firmware, which has caused others problems with syncing. I don't see anything in the logs that suggest problems.
Should I return the 320NS and get the 630NS? Will I see any IO improvement by adding a 4th drive to the array?
Thanks!
SM
