Gigabit Link throughput

As a rule of thumb in doing calculations, what figure would you use in Mbytes/sec? I know the answer varies grealty on the topolgy of the network but I wonde what newteok engineers use a rough rule of thumb?

Many thanks.

For the low end I'd put about 60 MB/s, or about half top speed. For the top I'd say 115 MB/s, since 120 are about the physical limit. Those figures hold true for net-only transfers or if you have adequate I/O infrastructure backing it.
