Re: TTM plots NCC->SARA for oct'99, may & aug 2000
Well,
the CPU graphs show the routers are OK for now. Although I guess they
would have problems if traffic doubles. I guess the figures will
improve more when the connection to the AMS-IX is upgraded to Fast
Ethernet. Currently the half-duplex 10 Mbit/s connection has the same
problems the transit and service lan had (too many collisions)
