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. > I admit, at one point I considered disabling it automatically for anything > under Gig speed, but a large community has used this driver with this > feature for over a year, no one has lobbied to have to disabled, so I > have not. 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?
