BootSpeed

Revision 2 as of 2011-04-28 17:32:18

Clear message

Summary

Iteratively investigate the boot process for preinstalled images on ARM. Find slow points or blockers. Optimise where feasible.

Release Note

Ubuntu 11.10 is now able to boot in ${TIME} on ${HARDWARE}!!!

Rationale

A full investigation to improve boot speed has been performed for i386, targeting the Dell Mini 9. This led to significant improvements in speed for many people, with many sorts of hardware. Compared to other software solutions, Ubuntu boots relatively slowly on ARM hardware: there may be architecture-specific reasons for this, which ought be investigated and fixed.

User stories

Assumptions

Design

You can have subsections that better describe specific parts of the issue.

Implementation

This section should describe a plan of action (the "how") to implement the changes discussed. Could include subsections like:

UI Changes

Should cover changes required to the UI, or specific UI that is required to implement this

Code Changes

Code changes should include an overview of what needs to change, and in some cases even the specific details.

Migration

Include:

  • data migration, if any
  • redirects from old URLs to new ones, if any
  • how users will be pointed to the new way of doing things, if necessary.

Test/Demo Plan

It's important that we are able to test new features, and demonstrate them to users. Use this section to describe a short plan that anybody can follow that demonstrates the feature is working. This can then be used during testing, and to show off after release. Please add an entry to http://testcases.qa.ubuntu.com/Coverage/NewFeatures for tracking test coverage.

This need not be added or completed until the specification is nearing beta.

Unresolved issues

This should highlight any issues that should be addressed in further specifications, and not problems with the specification itself; since any specification with problems cannot be approved.

BoF agenda and discussion

Use this section to take notes during the BoF; if you keep it in the approved spec, use it for summarising what was discussed and note any options that were rejected.
