Hi -

We're using a Sparc box to route 5 subnets. I'm looking for a way to
determine the efficiency of this setup (latency introduced,
bottlenecking, etc). Any suggestions?

Yes. First take some measurements through your SPARC router. These
can be simple like ping and ftp, or more complex like ttcp, netperf,
lmbench, or tcpbench. Run each test at least three times, and try
to measure as much time and data as possible.

Then relocate your test environment so that your only change is so
that you don't go through your router. Perform the experiments again.
Any difference between the numbers can most likely be attributed to
the overhead introduced by your router.

If you really want to learn something, test again with a different
router. You will learn the relative performance of various approaches,
which is probably why you are running benchmarks in the first place.
