Statistics/zh-cn

This page contains a variety of statistics about Fedora's usage. The Fedora Project believes that metrics are an important tool.

Who uses Fedora?
Lots of different people. Millions, in fact -- many millions! You can see some notable examples on the Overview page.

Fedora 16 (Verne)
Verne first ventured into the great unknown on 2011-11-08.

Accuracy of metrics
The numbers above, for yum, represent unique IP addresses that reach our update server, not simply downloads. We believe it is reasonable to equate a "new IP address checking in" with "a new installation of Fedora", with the following caveats:


 * 1) Users who have dynamic IP addresses will likely be counted multiple times, which inflates the number by some amount.
 * 2) Users who are behind NAT or corporate proxies will not be counted at all.

The anecdotal evidence that we receive from different groups, companies, and organizations suggests that group (2) is significantly larger than group (1). As such, we believe that the true numbers in the field are higher than the numbers on this page.

For a more thorough discussion and enlightening information about the measurement of Fedora's userbase, refer to this blog entry by Jef Spaleta.

Why is the Fedora 8 count so high?
We believe this is due to the high concentration of Fedora 8 images on Amazon EC2. We may see additional changes with Fedora 14 and later as that release is expected to be available on EC2 on release day.

Smolt Data
Smolt is Fedora's hardware profiling project. It is an opt-in database that tracks unique installations of Fedora, and various details about that install. People who install to runlevel 5 will be able to opt-in during firstboot, but people who install to runlevel 3 will have to install the smolt client via yum and manually register.

BitTorrent
The following table shows the number of downloads that have been made over BitTorrent. This table shows downloads only through trackers connected to the official torrent server.

Direct Download
The following table shows the number of direct downloads of media from unique IP addresses, as shown in the web proxy logs. The actual number of raw downloads tends to be much higher.

Contributors


In April 2008, the FAS (Fedora Account System) process was converted to a click-through process instead of a manual process of GPG signing and fax/email.
