Mirco Posted January 9, 2019 Share Posted January 9, 2019 Hi everyone, i've received my new Helios4, i installed OpenMediaVault and i've a 6TB WDRed inside Helios4. Trying to copy files on the NAS i found a very slow speed transfer rate (about 4.5MB/s) i tried to test the LAN over the Elios4 with iperf an this are the results... any idea to solve the problem ? Cables are new cat 5e.

gprovost Posted January 11, 2019 Share Posted January 11, 2019 @Mirco As discussed with you on FB, the mii-tool command you did confirmed that the Helios4 is connected at 1Gbps full duplex with your router/switch. $> sudo mii-tool eth0 eth0: negotiated 1000baseT-FD flow-control, link ok You did your iperf measure from a laptop connected by wifi to your router, so the perf you get is due to the low throughput with your wifi connection. Do your perf test with a computer or laptop that has a gigabit LAN interface. Link to comment Share on other sites More sharing options...
