It doesn't look like your router supports jumbo frames. Have you tried direct-connect?

Ok, are you sure you measured Mb/s and not MB/s?

The router is a fast ethernet router, which means maximum throughput is 100Mbit/s (or approximately ~10MByte/s). I'm pretty sure that iometer gives results in MByte/s, so, 10.5MByte/s means you've maxed out your switch.

System:
Intel QX6800 on Asus MB P5W64 WS Professional with gigabit LAN, no jumbo mumbo frames, running WinXP Pro sp2
2 GB memory, Areca 1220-Raid 6- pci-e(8x) card with 6x 250 gb drives.

Model: Infrant ReadyNAS NV+
Firmware: RAIDiator™ v3.01c1-p6 [1.00a034]
Memory: 256 MB [2.5-3-3-7]
Volume C: Online, 11% of 2010 GB used
X-RAID (Expandable RAID), 4 disks


4x Seagate ST3750640NS 698 GB, Write-cache ON, SMART+
Journaling: ALL DISABLED
Fast CIFS Writes: ON
All wired with Cat6 cabling

IO-Meter shows:
Reads: 27.6 MB/sec
Writes: 16.8 MB/sec


Does anyone know where this setting below is located ?
"Force CIFS filename case-sensitivity" ?? cant seem to find it :(
I read somewhere that disabling it would improve performance ?

Seeing all other results .. I should be happy with this result... :shock:
And I am not happy with the speed of it.. I expected more like the speed of the Raid 6 array on one of my video workstations (specs above)..
this reads 55.6 MB/sec and writes 48.2 MB/sec also over the network from other simular workstations..

Thank you all. My quote should have said MB/s. It was suggested the Etherfast 10/100 switch may be the speed limit. And, I should bypass the switch with a direct-connect. Finally...

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.

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.

I am using a Netgear GS108T 1Gigabit switch with a top notch quad core Intel setup running XP SP2. Jumbo frames is enabled.

READ: 31.98MB/s
WRITE: 24.91MB/s

Thought it might be a bit faster tho before I purchased it. But its ok, nothing special.

Also running X-RAID.

I connect to my NV+ using two different computers, and I noticed (with Retrospect) that they seemed to get very different performance. My main use of the NV+ is for backup using Retrospect.

I ran Iometer on both while directly connected to the NV+ (and separate times, of course). I used the tests specified at http://www.infrant.com/forum/viewtopic.php?t=265 .

The NV+ is configured to use jumbo frames. The disk write cache is enabled. Journaling is disabled.

Here are the results that I got:<ol><li>IBM ThinkPad T41 running WinXP Pro (SP2). The NIC is an Intel(R) PRO/1000 MT Mobile Connection with driver version 8.6.11.0 (6/29/2005). Jumbo frames are enabled at 16128 bytes (the highest setting offered). I got 7.285511 MBps for writes and 3.192311 MBps for reads. (The numbers without jumbo frames were 5.608709 and 3.170804, respectively.)<li>Dell Inspiron 600m running WinXP Home (SP2). The NIC is a Broadcom 570x with driver version 8.27.1 (8/31/2005). I did not see any configuration option for jumbo frames. I got 8.185093 MBps for writes and 26.862328 MBps for reads.</ol>Various questions come to mind:

Should I be getting better performance (for either or both computer)? If so, what should I be doing?

Is there something that I can do to improve the performance of the T41? Should try a different setting for jumbo frames (e.g., 9014 bytes)? Should I disable jumbo frames altogether? (I had noticed the original discrepancies when none of the computers, including the NV+, were using jumbo frames.)
Typically, the NV+ is connected directly to a NETGEAR GS105 switch. When wanting performance, the other computers are typically connected to the same switch or to a NETGEAR GS108 switch (which connects to the GS105). Both of these switches are gigabit, and I believe that they support jumbo frames. Is there anything that I would want to do to get best performance in the typical situation?

Hi there

Using a Core2Duo E4400 with a D-Link DGE-530T-GBIT-NIC and a Netgear GS108 GBIT Ethernet switch I get the following results:

Read: 29.598 MBps
Write: 12.243 MBps

Jumbo frames are enabled (9014), journaling is off, AV scanner disabled.

I am a bit worried about the slow write performance and at this moment I don't have a clue how to correct this.

I opened another thread at http://www.infrant.com/forum/viewtopic.php?t=12661 for my speed issue to keep this one clean.

olove - not sure if this is the reason, but please check the wiki for the maximum size of jumbo frames supported by the unit. It's < 8000.
