That is the reality of it. </div><a href="http://fedoraproject.org/sponsors" target="_blank">http://fedoraproject.org/sponsors</a> The mirroring system is tiered these days which helps save cost quite a bit. A lot of work is done voluntarily as well. Fedora is intended to remain always free as a community distribution. Red Hat is the primary sponsor and doesn't directly profit by Fedora but via Red Hat Enterprise Linux, a Fedora derivative. Rahul</blockquote><div> Which goes back to the point: DeltaRPM *SAVES* tons of bandwidth = money. You generate a deltaRPM *once* and directly reduce bandwidth usage ~50% or more for EVERYONE around the planet whom instead of 364 megs of updates after the first install of F11 would have used 182 or much less. (No need to answer, Rahul, this doesn't go to you but rather to those whom expressed doubts about DeltaRPM being a good idea). I can't believe there's still a need to explain the benefits of DeltaRPM two years down the line.... <a href="https://fcp.surfsite.org/modules/newbb/viewtopic.php?topic_id=36140&forum=10&post_id=162348#threadtop">https://fcp.surfsite.org/modules/newbb/viewtopic.php?topic_id=36140&forum=10&post_id=162348#threadtop</a> ================================================================= Full update gave me even better results!!! 75% savings !!!

There are millions of people with dialup and other slow connections on our planet and updates for them are almost impossible. Or students with laptops who can do some big installs when they are at their university but at home have also slow connection. For all of them bandwidth is scarce and deltarpms is a great solution to that problem so please do all you can with implementing it. Thank you in advance. Valent from Croatia. ================================================================= It is great no doubt and I have been using it for a few days now. Updating is no more that big a drain on the bandwidth.
