I think the issue here is that when we install a machine we expect it to
just work TM, we dont go looking at all the possible options for something
that "may" cause an issue.

Yes he spotted there was a problem, investigated and found a solution
but I'd guess this took a fair amount of time and hence is not something
we ant others to have to go through.

Much as this sounds like an option if TSP doesnt provide any real gains
at 100Mb, the main question is why should enabling this option have such
a massive detrimental effect on performance?

Surely this is work investigating and fixing? The issue could be
manifesting itself in other ways on 1Gb and 10Gb could it not? So a
fix could provide additional benefits.

The key issue I suppose is to understand why there should be such a
drop in performance, hardware, driver or OS issue?
