I disagree. In my experience simply many cards don't follow strictly the
ethernet standard. This means that if you use all realtek, or all 3Com, or
all whatever you want NICs in a network you usually get good performance.
If you mix different models (sometimes even if the chipset is the same!)
it's not so unusual to get performance problems. In this situations weird
things happen. Sometimes simply changing  a little the cable length could
change the situation, increasing or lowering performances. Probably the
cheaper chips are out of standard and the good ones are not, but I'm not so
sure of this.

Just my 2 cents.
