Do you have an abnormally large (non-default) MTU?  Or perhaps, a large
parallelization of the aforementioned file transfers?  Of course, small
packets can only fit in between large packets, and the routers are not going
to interrupt the middle of a large packet to make priority for the small
packet.  Even if you have traffic shaping, if you have an abnormally large
MTU, that would still slowdown the small packets.

Also - This seems obvious, I don't know why I didn't mention it before - 

The problem might be sporadic.  You say you measure 20-30ms roundtrip ping
response, but do you do that *all* day long?  Do you do that at the same
exact moment that people demonstrate the slowness happening?
