Hi,
we notice the same problem on nutanix platform.
running kernel linux-image-5.15.0-124-generic we get average speed of 130MB/s,
running the linux-image-5.15.0-125-generic the max I can reach is 3MB/s.
Nutanix also uses the virtio drivers:
$ lspci -v |grep -i net
00:03.0 Ethernet controller: Red Hat, Inc. Virtio network device
Subsystem: Red Hat, Inc. Virtio network device
Regards
