You may want to throttle the connection in Squid. It seems like the
connection is saturated, though under normal circumstances it that
wouldn't cause the level of trouble that you are seeing. It might be
worth investigating the settings on the IPCOP box.
Your theory about buffers could well be correct, but probably the
simplest thing to do is limit the maximum speed to around 95% of the
available bandwidth (may require some experimentation).
