tuxflux Posted September 2, 2018 Share Posted September 2, 2018 Hi. After the latest Unraid update I'm experiencing slow file transfers from my Mac (High Sierra) to my Unraid server. Before the update, it was pretty snappy, but now it's transferring to the cache drive (I've checked) at a measly 13/14 MB/S. If I use the terminal on the server or Dolphin GUI to transfer files from one disk to the other (my downloads folder to my movies folder), it transfers at full speed still, and uses the cache drive like it's intended to be used. I've tried with OSX compatibility on or off, but it seems like I'm stuck with slow speeds atm and it's very annoying. Any help would be appreciated. Update: I turned off the the cache drive and it's writing faster directly to the array (25 MB/S). So yeah, that's not normal lol Link to comment
1812 Posted September 2, 2018 Share Posted September 2, 2018 please be more specific about "latest update" if you mean 6.5.3 state that. if you mean 6.6.0rc 1, then post the issue in that appropriate pre-release section. otherwise, a bit hard to troubleshoot. Link to comment
John_M Posted September 2, 2018 Share Posted September 2, 2018 How is your Mac connected to the share - AFP or SMB? Are you writing to a user share with cache-yes or a disk share on cache? Post diagnostics. Link to comment
tuxflux Posted September 2, 2018 Author Share Posted September 2, 2018 SMB. I've used AFP in the past and it's been even slower. To 6.5.3 from whatever the official release was before that. No RC releases. Cache disk is formatted as XFS. Samsung 850 EVO PRO SSD. Have run TRIM commands. Cache for the share and globally has been enabled. I've just started the mover so I can format it to BTRFS, TRIM it again, and see if the speed improves. Which diagnostics would you like to see? Link to comment
John_M Posted September 2, 2018 Share Posted September 2, 2018 AFP performance and reliability are much improved if you move the Netatalk database (the .AppleDB folder in the root of the share) off the array and onto your cache. All you have to do is change the Volume dbpath like this: That aside, SMB works well with Sierra and High Sierra - in fact it's Windows 10 users who are having all kinds of problems with SMB at the moment. Do you have Enhanced OS X interoperability enabled? 37 minutes ago, tuxflux said: Which diagnostics would you like to see? Your unRAID diagnostics. Tools -> Diagnostics. Post the zip file.

tuxflux Posted September 2, 2018 Author Share Posted September 2, 2018 So my attempt at reformatting and trim made no difference. 11 MB/S writes and around 30 MB/S reads. I tried both AFP and SMB, and used your suggestion John. No difference in performance. OSX compat is enabled. Network wise everything is hooked up to gigabit ethernet except the laptop I'm currently using which uses AC wireless. I expect some performance loss with wifi obv, but it shouldn't be this severe. tuxieserver-diagnostics-20180902-1606.zip Link to comment
John_M Posted September 2, 2018 Share Posted September 2, 2018 So your testing was done over a wireless connection? There are too many variables there. Please retest with a proper cabled connection. Link to comment

Gonna see what I can do to ramp up my WiFi connection. Link to comment
John_M Posted September 3, 2018 Share Posted September 3, 2018 I'd use it for tablets and Kindles and such and put real computers on the wired network, even if it means buying one of those USB C to Ethernet adapters. There are lots of problems with using WiFi where there's any expectation of performance. The 2.4 GHz band is overcrowded. The 5 GHz band has problems with walls and floors. A wireless access point also behaves not like a switch but like a hub, where the bandwidth available is shared amongst all the devices connected to it. Link to comment
