Hello All I have been playing with FreeBSD 14.3-RELEASE and 15.0-REELASE amd64 qemu powered vms on a Linux cloud hosting setup. I have noticed that with VirtIO net ( vtnet ) interfaces there is some sort of tuning required , or there is some sort of limitation on the packets per second and overall throughput the nics can push. I am not able to get any one interface to push more then 6Gb/s bursts and 5.5Gb/s sustained. Before I go off the deep end with details has anyone run into this , is this a known issue ? -- mark saad | [email protected]
