Tuning for Supermicro X10SDV-TLN4F-O Mini ITX Server Motherboard

[erez]

Hi All,

Following several posts on the subject matter of slow CIFS including guides published by two notable members Cyberjock and Jgreco I am still stuck with slow performance (7 to 8 mbps) on a Supermicro X10-SDV-TLN4F-O mini Its motherboard with 4x WD 6TB SATA and 128GB ECC RAM running on the 1GE port.. NOT the 10GE port.

I've tried autotune and also disabled DOS attributes on the Auxiliary Parameters of CIFS (Thanks for the guide Cyberjock)

If anyone has some experience with this motherboard it will be greatly appreciated

Thanks in advance...
Erez

Also running iperf as per guide...(going through a switch)

Bump up the window size on both ends (-w 1M probably) and please don't use "-f k", if I haven't had enough coffee, it makes my eyeballs bounce trying to count the digits.

Thanks Jgreco...(really appreciate your help)
Please see below 1m on both sides still same network performance so network is not the best but still much better than 7 to 8 mbps I get on the CIFS

Okay, so something's clearly way off. What kind of client machine is this, and what kind of switch?

 

[erez]

Its going through a cyberoam and a cisco switch but to be honest i got the same results when plugging my laptop directly to the freenas port. My laptop is a lenovo thinkpad i7 CPU with 8GB RAM running windows 8.1 I also tried from a desktop i3CPU 8GB RAM running windows 10 and same results. Its a brand new supermicro motherboard and i get the same if going through either of the two 1GE ports. Above said iPerf confirms i should be getting 500mbps.. so has to be something in the freenas configuration?

 

[jgreco]

No, iperf merely suggests that you've got a network problem here. iperf doesn't "confirm" that you should be getting 500Mbps, it confirms that networking isn't up to snuff. A NAS storage system is only as good as its weakest link, and if you cannot get 1Gbps out of your network on reasonably modern gear, something is very broken.

You probably want to start checking to see where the problem is. If you can log in to a CLI on the QNAP, I suggest trying iperf from the QNAP to the FreeNAS which should give you a solid 1Gbps. If not, you probably need to start pulling things apart to figure out what's gimpy. Once you can get two devices that should-be-able-to-talk-at-1Gbps to do so, add further devices. Your laptop probably cannot actually hit 1Gbps, many of them use Realtek or other cheap ethernet chipsets. Your other desktop should be able to.

 

[erez]

Understood... will pull apart and hook PC directly to NAS to re-test. however at the same time why would CIFS only get 7 to 8 Mbps?

 

[jgreco]

It's hard to know until you know what's broken.
