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.
