Re: delta rebuild
it's a simple way to compare whether the delta RPM thing is
saving you
any time. If that speed is faster than your download speed, it is...
Do you mean there is a parameter a user can employ to control the balance
between network and processor resources for an update? I surmised the
object of the delta strategy was primarily to reduce data traffic at the
servers, with a secondary benefit of faster delivery to users with
small network bandwidth.
I have found the rebuild speeds displayed on my F12 test system
one-quarter to one-tenth of my network bandwidth. This has not been
onerous, but certainly time would be saved if I could say "Do not use
delta rpms." to yum.
Recent experience has delivered the worst of both worlds: about half the
delta rpms fail integrity checks, and complete copies of those files have
to be downloaded after the delta rebuild failures. An earlier post to
this list explained a format change causes these failures, and they will
abate as packages are rebuilt.
