Title: drop /etc/apt/apt.conf.d/90cloud-init-pipelining in 16.04+ Status in cloud-init: New Bug description: /etc/apt/apt.conf.d/90cloud-init-pipelining disables pipelining which causes a significant performance reduction in apt downloads. This should not be necessary in 16.04, as apt can detect broken pipeline responses, fix it, and disable pipelining for the next connection (it can also match the response based on the hashes, rather than just complaining the hashes are wrong). This is causing a significant performance decrease, as a small sample, firefox in a fresh lxd container: without pipelining: Fetched 81.1 MB in 6s (13.2 MB/s) with pipelining: Fetched 81.1 MB in 2s (32.2 MB/s) (400 Mbit/s connection, 25-30ms RTT, xenial LXD container) Related bugs: * bug 948461: apt-get hashsum/size mismatch because s3 mirrors don't support http pipelining correctly To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1794982/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
