/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) |
