It might, or it might make it worse. The absolute speed doesn't
matter, the relative speed of combined ingresses to egress matter.

If you have 10G ingress and 1G egress, you'll need lot of buffering.
If you have 5 1G ingresses pushing to 1G egress, you'll need lot of buffering.
If you have 1G pushing to 1G egress, you don't need buffering.
If you have 1G pushing to 10G egress, you don't need buffering.

I don't know which BRCM EX4300 runs, so I don't know how much buffer
it has. EX3400 is same era design and I think it's BCM565xx/firescout.
