Okay, I acknowledge the problem and admit you don't understand networking.
You have confused the slowstart feature (TCP) with ping (ICMP). TCP and
ICMP are what are called protocols. Slowstart has nothing to do with ICMP.

I will add that if you do an ifconfig I suspect you will see collisions on
your interface, resulting in poor performance. This is caused by running
the interface half duplex, and should not be used unless you are connected
to a type of obsolete hardware known as a hub, instead of a switch. If you
connect to a switch you should see zero collisions.

Finally, even 70ms is really poor ping time, I get better than that
between Albany NY and San Jose CA! Local ping time, even between Pentium
class utility machines on a thinnet (10Mbit half duplex technology) is
70-1400us on a somewhat loaded network.
