But this doesn't have anything to do with the hidden patch! It can be
multiple things:

o missing TCP segment offload support
o inefficient zerocopy DMA support
o IRQ routing problems
o wrong QoS settings

Could you please be more specific on what exactly you're trying to
achieve? Do you want to load balance an application whose average
package size is 80 bytes? How many sustained connections per seconds do
you have?

Best regards,
