The positive effect of traffic localization in P2P systems is widely praised as it allows to decrease the amount of traffic crossing inter-ISP links. At the same time its negative effect is often overlooked. In this paper we concentrate on the biased choice of peers as a way to localize traffic in P2P BitTorrent-like file sharing systems. We demonstrate, evaluate and discuss the negative effect of traffic localization expressing itself in the increase of the average file downloading time as the level of localization increases.
