Hi i have a very strange problem with the speed of the Ethernet connection with my Thecus W4000 Freenas server.
Tests with iperf3 are made between NAS device and the Ubuntu machine directly connected in a switch. Network runs at 1Gb. The cables and the switch are checked - they are not relevant to the problem. Test results are very strange and vary depending on which machine the iperf3 server is running on.
FreeNAS server - Ubuntu client = 146Mb/s
FreeNAS client - Ubuntu server = 515Mb/s
Originally, I bought this device with Windows Server 2012 and had no such issues until I installed FreeNAS. The only modification I've done is increasing the RAM from 4GB to 8GB. More information about the W4000 hardware
I searched the forum and saw that this hardware was used by others. Does anyone know how this can be overcome?
I apply the test logs in both directions:
