In P2P networks, clients both provide and use resources. This means that unlike client–server systems, the content-serving capacity of peer-to-peer networks can actually ''increase'' as more users begin to access the content (especially with protocols such as [[Bittorrent|BitTorrent]] that require users to share, refer a performance measurement study<ref>{{cite book | chapter-url=https://ieeexplore.ieee.org/document/6488040 | doi=10.1109/NCC.2013.6488040 | chapter=Performance analysis of BitTorrent protocol | title=2013 National Conference on Communications (NCC) | date=2013 | last1=Sharma | first1=Parul | last2=Bhakuni | first2=Anuja | last3=Kaushal | first3=Rishabh | pages=1–5 | isbn=978-1-4673-5952-8 }}</ref>).
