Hello.
On my PC, tap <--> bridge <--> tap networking gives 600 megbit.
Exactly the same, but -net socket,mcast gives about 1 megbit (!) I do not understand why.
In my mind, -net socket,mcast is the same as tap, but ethernet frames are going in much simplier way: instead of
qemu1 -> /dev/tun -> kernel/bridge -> /dev/tun -> qemu2
in such way:
qemu1 -> qemu2
Does somebody knows, why -net socket,mcast works so slowly?
People said, that VDE performace is like TAP. Why not to make same performace on -net socket,mcast ?
