Guest Slow Network Connection with Jumbo Packets
I have enabled jumbo packets everywhere in my network.
I verified that jumbo packets are enabled on the Hyper-V host physical NICs and Hyper-V virtual switch.
I tested pinging full size frames with no fragmenting from the Hyper-V host to another physical machine.
I tested Internet downloads from the Hyper-V host at full speed.
Inside the Hyper-V guest, if I leave jumbo packets disabled, all is fine.
If I switch the guest to 4K or 9K jumbo packets I get extremely slow LAN and WAN speeds.
Has anyone run into this before?
Thanks.
