I was wondering why I was getting so few deltarpms for big package updates (like libreoffice), and I went and checked the source[0] It turns out that in line 32 it removes the drpm if its size is more than half the non-delta size. Thing is, this criterion is really ill-suited for big RPMs (which is where deltas save the most bandwidth), since a DRPM on libreoffice could be more than half the non-delta size, but still save considerable bandwidth (hundreds of MB). So... why not use a different threshold? I propose 80% for packages bigger than 200k, and 50% for smaller packages. Pseudo-patch: @ -32,1 +32,5 - let drpmsize=$drpmsize+$drpmsize + if (( $drpmsize/200 < 204800 )) ; then + let ndrpmsize=$drpmsize+$drpmsize + else + let ndrpmsize=$drpmsize+$drpmsize/5 + fi [0] https://github.com/openSUSE/open-build-service/blob/master/src/backend/worke... -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org
