Boot performance work

Registered by Robbie Williamson on 2009-11-06

Work towards and maintain the boot time budget on reference hardware (Dell Mini 10 SSD & HDD). This will be done by regularly reporting our progress towards our 10 second goal for a Dell Mini 10 with SSD storage. Starting with Alpha1, we will measure and report our progress on a weekly basis, using a combination of bootgraph for the kernel allocation and bootchart for post-kernel to full desktop. Reports for both SSD and HDD storage will be posted under the Lucid section of https://wiki.ubuntu.com/FoundationsTeam/BootPerformance.

(Marking items as DONE once they hit the budget)

pitti, 2010-02-23: Discussed current desktop status with Rick and Robbie in today's team meeting. This is as far as we can realistically get in lucid on the desktop side, so considering this implemented now.
scott, 2010-02-24: Kernel+Plumbing+X hit 6s now which is the budget - it doesn't quite divide as we thought it would, because much of plumbing is waiting for the Kernel's i915 + fbcon drivers to load for the X server
cjwatson, 2010-03-12: Agreed last week to postpone the netbook-launcher work, as we're timing a bit differently and forcing that work would involve redoing a lot of it in 10.10.
