ACK - but that is yet-another set of variables of limited utility to an re(4)
coder. We don't know what MB, BIOS, 'glue' chipset, NIC ... yada yada.. Vista is
using - nor would it be lot of help as regards *BSD if we DID know.

Sure they are. But they have to be either quantized (hard) or removed (easy).

No need to write it.
tcpdump has lots of 'steering', dummynet has what you need, and wireshark may be
of use. More stuff yet is in ports.
But you still need two boxes, and at least two NICS - preferably 3 or more so
that you can do re to re and re to 'non-re'.

It *might* do if you can protect your friend's Vista from interference by
booting it from an outboard HDD or USB stick - even a 'LiveCD' that is a bit
better suited to providing analytical tools.

As they should.
Remember - I didnt say that re(4) might not have need of fixing - I just said
you were not the one best equipped to contribute good test data.

Perhaps. But, as said - it is mostly just a different set of confusables.

Lack of specialized resources is no sin.
But best to face that and concentrate your energy on issues that you can more
easily test accurately - not with what you wish you had - but with what you DO have.
Others will have access to better re(4) test environments - or the resources to
Meanwhile, I suspect that if you force your re to downshift to 10-base speed
when using the uplink, you will see real-world throughput actually go up, not down.
