zdude Posted April 26, 2017 Share Posted April 26, 2017 Hello i notice that when i copy files lets say 3GB ISO file, I am getting a network trans of 20kb. The Hard Drives i have are 7200 64MB Cache 1GB Network Card Connected to a 1GB 16Port Switch (with only 2 Devices on the switch) The Source server has two NICS teaming both Gig Nics My UnRaid has only one 1Gb Nic. as a Test I connected a 2nd server to the same switch running off SSD and moved File from the Server to the unRaid share. Same Speeds. What should i see with GIG-to-GIG 3Gb file Trans Rate? More than 20KB right? Any suggestion how to Rule out the network or the hardware? Quote Link to comment
Zonediver Posted April 26, 2017 Share Posted April 26, 2017 (edited) If you use NIC-bonding then beware, that the switch must support this - if not, then you have the answer, why the trasfer is slow. Edited April 26, 2017 by Zonediver Quote Link to comment

The Server that is teaming is only one of the two we tested from. Also when we first found this slow speed we added the 2nd nic but no change.. Once we tested on 2nd Source and seen the same thing i started to think it must be a setting or the unraid box or Drive speed because i did not add a Cache disk. I did not add one thinking the HardDrives are fast. Quote Link to comment
PikkonMG Posted April 26, 2017 Share Posted April 26, 2017 2nd NIC in unRAID will not speed up single file transfers from what I understand till SMB Multichannel support is added, and unRAID has to wait for it to become released and stable before it can be added. That is why you don't see a speed boost when bonding/teaming. Alternative is 10G Base-T which uses Cat6 so it's rj45, but cost is nutes and you would need a 10g switch also or option 2 is some good used mellanox cards which you can buy on ebay for cheep and do peer 2 peer. Quote SMB3 Multi-Channel ------------------ Samba 4.4.0 adds *experimental* support for SMB3 Multi-Channel. Multi-Channel is an SMB3 protocol feature that allows the client to bind multiple transport connections into one authenticated SMB session. This allows for increased fault tolerance and throughput. The client chooses transport connections as reported by the server and also chooses over which of the bound transport connections to send traffic. I/O operations for a given file handle can span multiple network connections this way. An SMB multi-channel session will be valid as long as at least one of its channels are up. In Samba, multi-channel can be enabled by setting the new smb.conf option "server multi channel support" to "yes". It is disabled by default. Samba has to report interface speeds and some capabilities to the client. On Linux, Samba can auto-detect the speed of an interface. But to support other platforms, and in order to be able to manually override the detected values, the "interfaces" smb.conf option has been given an extended syntax, by which an interface specification can additionally carry speed and capability information. The extended syntax looks like this for setting the speed to 1 gigabit per second: interfaces = 192.168.1.42;speed=1000000000 This extension should be used with care and are mainly intended for testing. See the smb.conf manual page for details. CAVEAT: While this should be working without problems mostly, there are still corner cases in the treatment of channel failures that may result in DATA CORRUPTION when these race conditions hit. It is hence NOT RECOMMENDED TO USE MULTI-CHANNEL IN PRODUCTION at this stage. This situation can be expected to improve during the life-time of the 4.4 release. Feed-back from test-setups is highly welcome. Quote Link to comment
zdude Posted April 26, 2017 Author Share Posted April 26, 2017 Less be clear I only added a 2nd nic to the source server to see if it would help. still getting 20kb/s (showing on the unraid server) when adding a 2nd nic did not work I tested a transfer from other source server on the same switch same 20kb/s What should i be expecting for for a transfer rate 1000MB port switch, 24port switch but only 2 computers on it.

PikkonMG Posted April 26, 2017 Share Posted April 26, 2017 (edited) 1GbE would be around a max of 125MB/s, but depending on cards/switch 100 to 115MB/s. This also depends on disk speed. SSD being fast and spindle or far slower. Sata 3 7200 RPM drive should do transfers somewhere around 125MB/s to 150MB/s local range I would think.

PikkonMG Posted April 26, 2017 Share Posted April 26, 2017 This is speed I get transfer from one WD Black to another to give a ruff idea on single drive 7200 RPM performance. z170 Chipset. Quote Link to comment
zdude Posted April 26, 2017 Author Share Posted April 26, 2017 whats that look like in system stats under network ? how many kb/s Quote Link to comment
PikkonMG Posted April 26, 2017 Share Posted April 26, 2017 If you're only getting 20KB/s something has to be really wrong. I'd go to Tools/Diagnostics and upload the file here for some of the guru's to look through. Quote Link to comment
zdude Posted April 26, 2017 Author Share Posted April 26, 2017 see attached I am copying a 3G file form Server A, win2008 R2 to Unraid direct over 1000Mb switch phsx0020-diagnostics-20170419-2119.zip Quote Link to comment
itimpi Posted April 26, 2017 Share Posted April 26, 2017 Are you sure that you Ethernet is coming up as 1GB. The speed you showed in the screenshot look suspiciously like what one would expect from a 100Mb Ethernet. It is always worth checking the Ethernet cable is not the issue. 1GB Ethernet requires 8 wires connected in the cable while 100Mb only requires 4. Therefore a bad connection in the cable can cause speed to degrade to 100Mb. Quote Link to comment
Zonediver Posted April 26, 2017 Share Posted April 26, 2017 Cable is a good idea to check - and try an other port on the Switch too - this rates are very low. If it would be 100MBit, you will see around 9,5MB/sek max and as mentioned bevore, 1000MBit will give you 92-115MB/sek. Quote Link to comment
PikkonMG Posted April 26, 2017 Share Posted April 26, 2017 Check cable, if you have a spare try to replace it. Also since you're using Seagate drives make sure that their is no jumper installed on the rear of the drives. Quote Link to comment
zdude Posted April 26, 2017 Author Share Posted April 26, 2017 The cables are Cat5 Store Made (not homemade) I just swapped them out with Cat6 just to rule them cable. Changed the ports here is the switch both are on Tripp Lite 16-Port Gigabit Ethernet Switch Rackmount Unmanaged Metal 1U.https://www.cdw.com/shop/products/Tripp-Lite-16-Port-Gigabit-Ethernet-Switch-Rackmount-Unmanaged-Metal-1U/4409178.aspx#PO Quote Link to comment
PikkonMG Posted April 26, 2017 Share Posted April 26, 2017 Is link that the unRAID server is plugged into green or amber? Quote Link to comment

Green When you do a file copy in windows its showing 11.1Mb/Sec But i dont really trust Windows Copy speed numbers. what do some of you see ? in windows and from unraid at at the same time.

Zonediver Posted April 26, 2017 Share Posted April 26, 2017 (edited) Wenn i copy between my Windows machines, i see up to 118MB/sek (944MBit) - 1000MBit-LAN in my home. Wenn i copy data from or to my unraid server, i see max. 95MB/sek (760MBit) , but i use an old Intel Pro 1000 PCI NIC - so thats normal. Your 11,1MB/sek means max. 88.8MBit.

zdude Posted April 26, 2017 Author Share Posted April 26, 2017 I may have fixed the issue. I rebooted the PC to check i had the most current BIOS (I DID) and now i am getting 961.8MB/S. thanks for the help.. Quote Link to comment
zdude Posted April 26, 2017 Author Share Posted April 26, 2017 much better, dont know what happen but its better. Quote Link to comment

From Tipp Lite wesite "Power LED (Green for Power On); One LED per RJ-45 port (Green indicates 10/100Mbps link; Amber indicates 1000Mbps link; LEDs flash to indicate port activity)" Good that a reboot worked for you. Next time if it happens again try another reboot, or it could be an issues with the switch green power feature. I had a TPLink at one point that would get stuck in green energy mode and I would have to unplug it and plug it back in. Edited April 27, 2017 by PikkonMG Quote Link to comment
