February 26, 20215 yr I know this topic has been beat over the head numerous times...but I'm not finding an answer that works. I am averaging about 40-50 Mb/s copy on the network to & from and even from CACHE to array or array to CACHE and in VMs. Even copying from CACHE in VM TO the VM is slow!! (And VM is ON the CACHE!) Jumbo frames not on. I have tried with DOCKER off. I have tried without a network bond. I have tried different ports/cables and all of that. Gig network running all Unifi gear. I have used Tips & Tricks to set: Disable NIC Flow Control? Yes Disable NIC Offload? Yes Ethernet NIC Rx Buffer:Default Ethernet NIC Tx Buffer:Default Ethernet NICS: eth0,eth1 iperf is showing VERY good speeds from my Win10 device to UNRAID...what the heck am I missing!!?? Diags attached along with a video of a transfer.
