Poor network performance in 5.4 AMD64 Snap 8 with SMP support

I have a server with a Supermikro mainboard and two Xeon 3.0Ghz/2MB. When
running kernel with SMP support the network performance is very poor, this
is very visible on NFS traffic. When running UP kernel the performance is
as espected and very good.
I have tried some different GB nics and the problems is static and
independent of modell/brand.
I have also disabled as much as hardware possible, no usb, sio and etc.
Typical indicator is also that the load on the box is skyrocketing when it
starts to serve nfs client, but the cpu load is very load.
Is there any way around this problem?
