Maybe my situation is different for some odd reason. I have my setting at max. The highest out going rate I've witnessed from my computer is 75% of my upstream capacity. That leaves 25% for Xolox and ACKs, general overhead, etc. When someone with a good pipe pulls files from me, I see no performance loss in my downloads. My download speed remains the same. I'm leaving my setting at max so someone can get a file if they need it. I'd rather have them in and out in a few minutes than have them nibble at me for three days.
