What kind of queuing are you using?

It sounds like configuring fair-queue on the interface (if your platform 
supports that, usually the ones with 2M interfaces do), it should help 
with the problem you're describing.

If you have CPU to spare, configure fair-queue everywhere you can where 
you don't have a "better" QoS-configuration in place. It really solves a 
lot of the problems people are seeing with FIFO and mixed traffic.
