August 4, 20196 yr I am getting inconsistent read speeds from my Unraid server, and as such having issues with media playback. I am certain the network is ok, as this is same hardware that was running a windows 10 machine, which would saturate gigabit. copying a 10GB file will start at about 1MB/s the increase to about 95MB/s for maybe 30 seconds then drop to below 1MB/s for about a minute and fluctuate back and forth. The Destination PC is has an SSD and 32GB RAM so it's not bottlenecking there. The same is happening when I perform a check on the 10TB parity drive, fluctuates sometimes telling me it will take 22 days to complete. I am not getting any high CPU or RAM usage on the server RAM is at 8% CPU load 5%-20% i7-4770 @ 3.40GHZ 32GB DDR3 Please help Video 1 - Copy / Read Video 2 - Parity check Edit 2: This also happens when copying from share to share. Speed is maxed out 150mbs+ then stops, zero for about half a minute, then full speed, then slow. urserver-diagnostics-20190804-2224.zip Edited August 5, 20196 yr by TheBuz

Thank you but all of those issues happen when I am not running a parity check When copying from share to share, it started at 800+ MBs then went down to 150 now just fluctuates between 5MBs http://imgur.com/a/poOGbIr
