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=265Please 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:Stock NV4 x Seagate ST3250823AS 250gb Hard Disk in X-RAIDAll journaling disabledFast writes onIntel D805 2.66ghz dual core cpuIntel D945GNTLKR motherboard with onboard Intel Gigabit NIC2 gigs ramSeagate ST3250824AS 250gb Hard DiskWindows Vista x86 RC1 (if that makes a difference)Dell PowerConnect 2708 Gigabit switch (no jumbo frames)Cat 6 cablingIO Meter Write: 19.321793 MBpsIO Meter Read: 26.803979 MBps

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.

PentiumD 3GHz 2GbRAM, LinkSys BEF SR41v4 Etherfast CableRouter with Cat5 cable

NV+ 1024Mb RAM, 4 disks X-RAID 500Gb Seagate ST3500630AS, Radiator 3.01c1-p6, UPS monitored, enable cache, disable journal, fast CIFS, Speed Auto-Negotiation, Smart disk check without problems.

Averages of several standard IOMeter protocol runs with and without jumbo frames enabled on NV+ (no difference) yielded...

MB/s Write=10.5
MB/s Read==9.0

Direct-connect:

Jumbo off, enable cache, disable journaling, CIFS writes, on UPS. Run both standard and with the maximum disk size quadrupled to 8192000 sectors with only a small difference.

MB/s Write 22
MB/s Read 44

Does this diagnose the venerable LinkSys BEF SR41v4 Etherfast CableRouter 10/100 switch as the speed limiter or bottleneck? Thank you.

brendan replied:
Yes. It's not a deficiency of that particular switch, it's just that a 100 megabit switch can only move data at up to 100 megabits, which is what the original numbers were showing. If you want to get closer to the direct connect speeds, you need a 1000 megabit (aka gigabit) switch instead.

Pardons for that not being exact but I edited out the duplicate gear talk. The story is that after the above testing, I bought an SMC GS8 Gigabit switch and plugged the NV+ and computer (Intel Pro 1000 switch) into the GS8 with Cat5e and re-ran as before (no jumbo frames).

write 19 MB/s
read 33 MB/s

It's not as good as some but far better than before getting the Gigabit switch. I don't understand why the direct was a little better before but am not going to sweat that. Thanks brendan and everyone.

Im on wireless N right now. Copying some m4v files to my NV+

Doing around 10 or 11MB/s for writes. Reads are around 15 or so.

I use a mac pro & airport extreme N (fast ethernet). All on AFP.

I had some pictures but i cant post them because of spam prevention :(

I wouldn't expect any better numbers over wireless N.

Agree. I think these numbers are quite good for wireless.

I wasnt expecting more :)

I also plugged it directly in my mac pro and was getting around 23MB/s for writes and 45MB/s for reads. Think ill pick up a gbit switch or something and use the wireless solely for notebooks/appletv.

Maybe you can share your network recipe with other Mac users 8)

I followed all the instructions but I am get an error "Worker 1" on "JJG" cannot set specification NV (the name of my test file). The largest request or reply size (262144 bytes) may be too large.

Any idea what I am doing wrong?

Ok. I got it working but the results are not pretty.

System:
Pentium 4 (3.2 GHz); 3 GB Ram; XP Pro
Intel PRO/1000 CT (jumbo frames disabled; link speed - auto detect)
Netgear GS608 switch
ReadyNas NV running RAIDiator 4.00b9-p1-T1 [1.00a037] in XRAID; 1 GB RAM
4x Samsung 500GB ; 75% filled
Disk write cache: ENABLED
Journaling: ALL DISABLED
Fast CIFS Writes: ON

I am getting around 10 MB/s on both reads and writes. This can't be the fastest speed I can get.

What should I change to improve the speed? I was wondering if my NIC card is the bottleneck. I can't see the switch being an issue since it is a gigabit switch. I am assuming I don't need to set anything on it since the NV reports 1000Mbit / full duplex.

Can someone give me a couple suggestions?
