July 1, 20224 yr Hey @ all. lately i've noticed that my read speeds are around 78,5mb/s and very constant. writing still runs arround 110-113mb/s no matter if i write to cache pool (2x 1Tb ssd) or directly into the array. parity checks are running extremly fast so no read problem with the discs or adapter itself i guess.. nothing changed besides newest stable build of Unraid 6.10.3 i've attached my diagnostics and hope someone is able to help me. thanks alot tower-diagnostics-20220701-0705.zip
July 1, 20224 yr Community Expert Start by running a single stream iperf test in both directions to see if it's network related.

July 1, 20224 yr Author Thanks just installed and tested. iperf3 shows the same problem.

July 1, 20224 yr Author also changed cat7 cable and switchport. did not solve problem. server has been rebooted also. my client is able to get full gigabit speed with speedtests over WAN and downloading stuff from WAN Edited July 1, 20224 yr by desertfox_0815

July 1, 20224 yr Author Any idea how to find the problematic part? Rebooted Unraid, Switch and Client. changed Switchports and cables.
July 5, 20224 yr Author Changed to a 1Gbit dual-port Intel server nic. was running perfect with full speed. i've filed a warranty claim with the mainboard seller. Board will be exchanged. Thanks alot
