  You haven't told us anything about the network infrastructure, except that
the problem doesn't affect (some) other machines on the network.  SO it's
probably not a problem with broadcast storms or excessive collisions, and
that leaves (a) wrong link speed, possible only on a switch (and unlikely to
yield the times given) or (b) excessive retransmits due to errors.
  Transmission errors are likely to reflect a piece of network hardware going
bad -- the NIC, the hub/switch port it connects to, or the cable between them.
