1)I really need to know the link bandwidth, so I can calculate
how much time to transmit certain amount of data.
If it's a gigabit link, why are those rxBandwidths and
totBandwidths just tens of bits per second? I looked through
the source code etherlink.cc, does the link bandwidth equal
sim_freq/ticksPerByte?
This is the bandwidth your application achieved. For example, think of a
real gigabit ethernet link. Usually, you're not actually sending 1Gbps on
that link.
2)Is the execution time on testsys equal to
(drivesys.cpu.numCycles/2GHZ)? In M5 simulator,
does 2G mean 2*2^30 or 2*10^9?
For bytes, G is 2^30, for everything else, it's 10^9
