I'd next try to tweak the txqueuelen (at the netvm side): sudo ifconfig vifxx.0 txqueuelen xxxx Appvm side (eth0) seems to have 1000 but the other side (vifxx.0) has only 64 by default that seems a bit small for high-performance transfers. -- i. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
