Well, I think it does not make sense to think about this in absolute terms. Thinking about user stories is better. A stable series user will be mostly upgrading packages from -security and -updates. The download speed and/or size of debs does not matter much in this case, as these are scheduled to be done in the background over the course of the day, via unattended upgrades download timer. Installation speed matters, as that is the window of time when the system is actually somewhat in a maintenance mode / degraded performance (apt is locked, there are CPU and disk-io loads). New instance initialization - e.g. spinning up a cloud instance, with cloud-init, and installing a bunch of things; deploying juju charm / conjure-up spell; configuring things with puppet / ansible / etc => these are download & install heavy. However, users that do that heavily, will be in a corporate / bussiness / datacentre environment and thus it is reasonable to expect them to have either a fat internet pipe, and/or a local mirror. Meaning download speed & size, are not critical. Then there are devel series users, developers who do sbuild builds, etc. These users are most likely to be on slower home-user connections and watch things a lot more closely interactively, who indeed care about the total download+install time. These users, are most likely very vocal / visible, but are not ultimately the target audience as to why we develop Ubuntu in the first place. Thus I would be willing to trade personal developer/devel-series user experience, in favor of the stable series user. I'm not sure how much it makes sense to proxy/cache/local-mirror devel series, if it is only a single machine in use. -- Regards, Dimitri. ps. I fight for the user pss. /me goes to setup a local mirror proxy cache, with dns spoofing to make sure all my sbuilds / lxd containers / VM / cloud-images use local mirror out of the box -- ubuntu-devel mailing list ubuntu-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel
