Over six months of surveying, CacheLogic found that Kazaa use had slipped far behind rival BitTorrent, which accounted for 53% of actual peer-to-peer network traffic. It found also that overall traffic has not been falling, as some have suggested. By June, an average of 8 million users were online at any given time, sharing a petabyte (10 million gigabytes) of data. Network monitoring firm BayTSP said the average number of people on the FastTrack network, which is dominated by Kazaa, held steady in June at about 2.7 million users at any given time. eDonkey, use of which has risen sharply in the last year, held at about 2.2 million average users, the company said.
