The following performance observations are also relevant:
•ESnet hosts in general have good packet loss (median 0.79%).
The average packet losses for the other groups varies from about 4.5%
(N. America East) to 7.7% (International).
Typically 25%-35% of the hosts in the non-ESnet groups are in the
poor to bad range.
•The response time for ESnet hosts averages at about 50ms, for
N. America West it is about 80ms, for N. America East about 150ms
and for International hosts around 200ms.
•Most of the unreachable problems are limited to a few hosts mainly
in the International group (Dresden, Novosibirsk, Florence).
•The unpredictability is most marked for a few International hosts and
roughly tracks the packet loss.
