October 20, 20187 yr G'day, I've noticed since upgrading to 661, that my local network transfers are bottlenecking at 5.6MB/s. This is both local file transfers and incoming internet data transfer (eliminating unraid drive array issue). Inter-drive transfers within the server hit the expected 100MB/s odd transfer rate (again, showing there isn't an issue with the drive array). I first noticed the issue when trying to transfer some files to the Unraid server. Then I noticed downloading on one LAN computer (assuming max saturation), then trying to stream from the Unraid server to another LAN computer. The second machine wouldn't stream at all UNTIL I paused the download on the first computer. NIC config note:: Unraid Server connects to gigabit smart switch. PC 1 is connected to a dumb gigabit switch that is connected to the gigabit smart switch. PC 2 is connected to the gigabit smart switch. Here are some screenshots of the various network configurations... etho0 is the local network NIC connected directly to a DLink Smart Switch. Having looked through the forums for solutions, I found some tips like checking the 'Tips and Tricks Tweek' app settings to ensure that NIC flow control is turned off. I tried it both enable and disabled to no effect. Another was to try different cables / connectors... So I made a fresh 1m cat6 cable and connected it back in. No difference there either unfortunately. I checked the DLink Smart switch that it is connected directly to; but that is all showing Full Duplex mode on all ports and the light indicators reflect this as well. Through Sab in docker, I can max out my download connection of 11MB/s... So I know there isn't anything wrong with that NIC side (onboard NIC). I am at a loss for what I can try... I've attached the Diagnostics zip file as well. kindrednetwork-diagnostics-20181020-1240.zip Edited October 20, 20187 yr by Sovaka Issue Resolved
October 20, 20187 yr Community Expert There are some issues with Realtek NICs on v6.6, first thing to try is updating to v6.6.2, v.6.6.3 when available will have some more Realtek related patches, also if you have one try using an addon NIC, Intel preferred.
October 20, 20187 yr Author Checked this morning and 663 was available... After updating and restarting Unraid, all is good. Thanks for the info re: Realtek hardware. In the future I will look at getting Intel NICs. Cheers.
