Perhaps we have two issues here: - the download during installs or first index update is 6-7MB extra, which makes a real difference when installing lots of computers - downloads from security.ubuntu.com being slow (eg 1-5KB/s) as it's >500ms away
The 20% additional download due to sources [1] would help both issues, but perhaps of bigger impact, trusting the country-level mirror for the security updates?
