October 17, 20169 yr Hi Chaps, I decided to upgrade my rig with a new MB, CPU and Ram (see sig) because I have been getting slow file transfer since as long as I remember (~ 15-20 MB/s) and the occasional pause whilst watching movies on my Dune. Also when transfering files from my Win10 PC to the server it would often become unresponsive or crash explorer. I thought maybe my old hardware was the bottleneck (Q6600 CPU, ASUS P5E-VM HDMI), hence the upgrade. Now I have my new build in place and things seem to be much worse (~1MB/s!!!) so I must have really screwed something. I don't think it is related to the network because moving files between disks on the array is the same speed. Below is a lan speed test from my PC to my Movies share. --- Lan Speed Test --- Version 1.3.2 OS Version: Windows 8 Processor: Intel® Core i5-4460 CPU @ 3.20GHz Date: 10/17/2016 Time: 09:32:10 Program Parameters: 0 High Performance Timer: 0.0000003207 Test File: Y:\Movies\NW_SpeedTest.dat (500MB) Write Time = 9.0542174 Seconds Write Speed = 441.7830720 Mbps Read Time = 211.6527515 Seconds Read Speed = 18.8988800 Mbps --- Any ideas? Thanks. Adam server-diagnostics-20161017-0917.zip
October 17, 20169 yr Author Any help, pretty please? Really struggling to work out what is wrong Thanks!
October 17, 20169 yr Community Expert Try copying to to different disk shares, is speed low on everyone? e.g.: \\tower\disk1 \\tower\disk2 \\tower\cache
October 17, 20169 yr I don't think it is related to the network because moving files between disks on the array is the same speed. Below is a lan speed test from my PC to my Movies share. Are you copying the files between disks through Midnight Commander or a Docker like Dolphin? If not, your network is still involved, as you will be copying files from disk1 -> PC -> disk2. If you are just doing a copy from your PC, try it using MC or Dolphin and see if the speed is different. Might be another useful data point in trying to isolate what the problem is. Also, your tag line mentions an SSD, but you are using a platter drive for your cache drive. It would definitely improve your write speeds (well, the perception of your write speeds anyways), if you used the SSD as your cache drive...
October 17, 20169 yr Just for sanity's sake, can you test your network performance between two other devices and make sure you are getting full gigabit speed? And across different ports on your router/switch? It's worth eliminating that possibility.
October 17, 20169 yr Author Thanks guys, I am currently testing each disk but it looks like the same issue on all drives so far. -- Test File: \\server\cache\NW_SpeedTest.dat Write Time = 1.8979300 Seconds Write Speed = 421.5118560 Mbps Read Time = 22.2038863 Seconds Read Speed = 36.0297280 Mbps Test File: \\server\disk1\NW_SpeedTest.dat Write Time = 2.5200097 Seconds Write Speed = 317.4590880 Mbps Read Time = 30.8942960 Seconds Read Speed = 25.8947440 Mbps -- I'll test using Dolphin now. EDIT: And network speed from another device,
October 17, 20169 yr Author Using dolphin to copy a 3gb file between disk9 and disk1 gave an average speed of 11.2 MiB/s
October 17, 20169 yr Your Ram configuration is odd. You do use 3 Sticks? Or are there more like in a Kit etc.? I know this is Not related that much but i know of very odd behaviour if Not all Channels of a cpu are used or uneven distributions are used.
October 17, 20169 yr Author Hi, yes I'm a bit of a nube, I thought I could use 3 because 24gb is plenty. They should only be used in pairs then right?
October 17, 20169 yr Hi, yes I'm a bit of a nube, I thought I could use 3 because 24gb is plenty. They should only be used in pairs then right? See attachment.. straight from your motherboard manual..

October 17, 20169 yr Just use 2 RAM sticks and put them in the yellow slots.. if you buy another one, you can fill the other 2 slots..
October 17, 20169 yr Author I really appreciate your help but are we talking about the same motherboard? See page 17 of the manual: http://download.gigabyte.eu/FileList/Manual/server_manual_mu70-su0_en_1002.pdf Thanks. At the moment I have my Dimms in the top three blue sockets.

Sorry, I looked at your old motherboard.. lol.. let me check..
October 17, 20169 yr Looks like you should be fine with the first 3 slots filled according to the manual..
October 17, 20169 yr 1st three or the first three blue ones? I have no idea lol In your picture the top 3 they should be labeled DIMM_P0_A0/DIMM_P0_A1/DIMM_P0_A2
October 17, 20169 yr Your network sounds like it is the bottleneck, but you'll definitely get faster file transfers if you perform them on the server itself, likely using rsync. From the SSH terminal of the unRAID instance: rsync -va --progress /mnt/diskN/folder/ /mnt/diskT/folder/ Where folder names are the same, and diskN is the source and diskT is the target. Then spend some time watching crap scroll by for hours, or find something else to do. It should go as fast as the bus can transport data from one drive to another if you do it locally. If you're "moving files between shares" across the network, it's still bottlenecked by your network reading the files to the machine doing the copying, then writing them back to the server.
October 18, 20169 yr Author I haven't had a chance to move the Ram around yet but we had a power cut last night. I decided before i change anything else to do some transfer tests with files (across network) to see where I am at. -- Test File: Y:\Movies\NW_SpeedTest.dat Write Time = 12.0347590 Seconds Write Speed = 664.7411840 Mbps Read Time = 8.5716386 Seconds Read Speed = 933.3104640 Mbps -- Huge improvement from yesterday, around 112MB/s in real terms each way which is more than double i have ever had! w00t! So that would seem to imply the bottleneck was the network as the power cut meant my switches and router were rebooted. I did try power cycling then at various stages but it may be one or the other is on the way out. I'll not call this solved yet as I'd like to get to the bottom of it but thank you all so much for your help!! Adam
October 18, 20169 yr Author Oh great, I moved the Dimms to the top three slots as suggested and now the MB light won't even come on, it is completely dead. Tried switching them back and just putting one Dimm in. Tried new power cable, different power socket, zip. Argh! EDIT: I can't believe it is the PSU, seems like too much of a coincidence, what do you think??? Current PSU is a good one: 650W Seasonic X-Series, 80PLUS Gold, not sure how old, 3 years plus I guess. Any simple tests I can run? I have a multimeter somewhere. Thanks. Adam EDIT2: I left it unplugged for a while then tried again and the MB light comes on for a couple of seconds before going off again. According to the manual: On - BMC firmware is initial Blinking - BMC firmware is ready Off - AC loss So PSU failure or something else??
October 18, 20169 yr Author Weirdly the motherboard light just started flashing so i booted up (all dimms in top three slots). Annoyingly I am back to slow transfer speeds again.
October 18, 20169 yr Could it be you're operating at Half Duplex on the network by negotiation? (Just throwing that in there)
October 18, 20169 yr Author Could it be you're operating at Half Duplex on the network by negotiation? (Just throwing that in there) hi, I don't think so, here is what unRaid sees:
October 18, 20169 yr Author I just tried changing switches and that has no made any difference, same with cables. Could it be the router?
October 18, 20169 yr Yes, it could be. How is your network configured, i.e. what is plugged into what?
