June 12, 20233 yr Hello, I am getting low transfer speeds (25-32mb/s) when moving files across the network. The network is gigabit, the unraid server is hardwired and the system I am testing from is connected via Wi-Fi 5, WPA3-Personal, TX/RX 866/866 on the 5GHz band. The drives are 5 WD blue 8tb with two in parity. The parity drives have been removed temporarily during troubleshooting. I ran DiskSpeed And also iperf I also took two sets of diagnostics, one ran during iperf and the other during a Win file transfer mononoke-diagnostics-20230612-1126_WIN_TRANSFER.zipmononoke-diagnostics-20230612-1125_IPERF.zip I am unsure what or where to look next, my searches haven't been very fruitful.

June 12, 20233 yr Author Alright, I feel a bit dumb but I tested on one of my laptops which has the same link speed (866/866) and am getting an average of 542Mbits/sec. I'll see what I can find, but what would typically be the reason for this? How can I maximize the speed on both my laptop and desktop?
June 13, 20233 yr Author I've been searching and reading posts all day and I can't find anything that would fix this speed issue, does anybody have any input? I've disabled as many services/processes as possible including AV/etc, updated my adapters driver, uninstalled and reinstalled the adapter driver, all with no change.
June 13, 20233 yr Those are WiFi relate, even link rate was 866M, it doesn't mean the bandwidth was 866Mb/s, and if got 542Mb/s is almost some kind best figure ( 2xxMb/s also a normal value ). You may try increase the WiFi channel width to 80Mhz or 160Mhz if AＰ and laptop support that. Edited June 13, 20233 yr by Vr2Io
June 13, 20233 yr Author I appreciate the response! The 5GHz channel was initially at 80Mhz, no change in speed when switching to 160Mhz. What's bothering me is using speedtest.net, I can get a download speed of 510Mbps, yet the data transfer from desktop to NAS is almost half of that.
June 14, 20233 yr 8 hours ago, dhahnke said: I can get a download speed of 510Mbps Pls try read a file from Unraid in several times, does close to 510Mbps ? If yes and only writing to Unraid got slow, you should try enable "reconstruct write".
