Just got my UnRaid up and going this weekend and so far it's been smooth sailing, my only concern so far  is the (seemingly) slow network performance/copy speeds.

I have parity enabled and have activated three user shares and each have been set to high water/1

I am getting speeds of 7-10MB/s from a Windows 7 machine to the UnRaid with the unraid share/drive mapped and using Teracopy.

performance is worse on my Mac OSX machine, getting around 3MB/s

These speeds are copying large video .iso files 4 to 14GB from local drives (the Mac drive is an SSD)

 

I have searched around the forums and haven't been able to find anything specific to check and haven't really been able to find a "benchmark" to compare my speed to, so any help from the community will be greatly appreciated!!!

 

Here's my set-up:

UnRaid:

Motherboard: Gigabyte G31M-ES2L

CPU: Celeron 430 / 1.80GHz  / Core: 1.35V  /  FSB: 800MHz / L2 Cache 512K

Ram: 1GB Ram (1x1GB) - Corsair Twin2X2048-64000C4 DDR-800, installed on/in a single channel

NIC: Onboard Gigabit:  RTL 8111C chip (10/100/1000 Mbit)

Parity Drive: Seagate Barracuda 1.5TB 7200 RPM 32MB Cache SATA 3 Gb/s

Data Drive (1): Western Digital "Green" WDC_WD15EARS 1.5 TB, SATA 3 Gb/s, 64 MB Cache (this is the model with 4k instead of 512b sectors)

 

Network:

Router: Netgear WNR3500L Gigabit "Open Source Router" (that's what is says on the box)

Switch: D-Link DGS-2205 Gigabit 5-Port Switch

Cabling: Generic Cat 5e

Thanks,

Post a syslog.

I've attached the syslog

syslog-2008-04-10.txt

Here's some more network specific info attached.

Network_Info.txt

Your hard drives are all configured as UDMA/133.  This means they are running in IDE Emulation mode.  Go into your BIOS and change the SATA type to AHCI.  This will allow the server to use the full SATA II speeds.

 

Also be aware that your motherboard is installing HPA partitions on your drives.  Search HPA on these forums to find out about the risk in that.  If you aren't able to disable your motherboard's HPA function (generally in the BIOS as something like 'save BIOS to disk), then you may want to replace your motherboard.

 

This is also weird, I can't really explain it:

 

Jul 25 21:38:46 unRaid kernel: 123MB HIGHMEM available.

Jul 25 21:38:46 unRaid kernel: 889MB LOWMEM available.

 

Those numbers seem switched to me.  Maybe there's an issue with your RAM?  I'm not sure, others can advise.  Normally RAM issues will cause instability (random restarts, etc), not slow speeds.  So I'm not sure if this is even a problem.

Well I happened to have another mobo lying around, a XFX nForce 680i LT and switched everything over onto it but now I can't get unraid to see any of my hard drives. syslog attached.

This is very frustrating  but I am determined! (That is If you guys can help me please)

Yeah, there's definitely something wrong with your second motherboard:

That board isn't listed on the Hardware Compatibility list, so it may just plain not work with unRAID.

 

Your original Gigabyte board is listed on the Hardware Compatibility list, however, so you should be able to get it working.  Did you try the BIOS changes I suggested?
