ltoolio Posted October 23, 2016 Share Posted October 23, 2016 Hey all, I'm experiencing some pretty poor network transfers between my primary PC and my Unraid box (10 MB/s). Steps I've taken to address: 1. Verified both computers show 1GBs for network. 2. Tried two different switches, both of which are gigabit capable 3. Tried multiple cables between the computers and the switch, all of which are gigabit capable. 4. Tried two different NICs on my Windows PC, both of which are gigabit capable. 5. Tested Read/Write Speeds on my Windows PC. Results are excellent. 700+ MB/s for each. 6. Ran the drive speed script that's floating around in the forums here for my SSD cache drive. 250MB/s+ 7. Created a share on my cache drive only. Got the same transfer result. 8. Created a share on one of the drives in my array. Got the same transfer result. So...I'm at a bit of a loss here. Not sure what else I should test. Any thoughts? Quote Link to comment
Squid Posted October 23, 2016 Share Posted October 23, 2016 10MB/s implies that the server is only connecting at 100Mb/s Post the diagnostics Quote Link to comment

John_M Posted October 24, 2016 Share Posted October 24, 2016 Do you have Jumbo frames enabled on some but not all of the hosts on your network? Quote Link to comment
ltoolio Posted October 24, 2016 Author Share Posted October 24, 2016 I don't believe I had it on, but I went ahead and set 7k MTU on both the Windows PC and the Unraid box. No change. Quote Link to comment
John_M Posted October 24, 2016 Share Posted October 24, 2016 An MTU of 7k is very non-standard. Better to set everything to the default 1500 because Jumbo frames are not backwards compatible. Quote Link to comment
