Is upstart ready to handle parallel startup and become a true event-driven system? I recall some discussion on that during F10, might want to get Casey Dahlin to weigh in on that.

The Scope section of this feature is somewhat lacking. One of the items that we're looking for is "what would constitute success or failure of this feature", rather than simply a list of packages that must be modified in order to implement. --[[User:Jstanley|Jstanley]] 03:22, 2 January 2009 (UTC)

There have been reports that when using SSD drives, readahead only makes the performance worse (because there's 0 seek time with SSD drives). There should probably be an option to disable readahead easily -- or even automatically.

[edit] Is upstart ready?

Is upstart ready to handle parallel startup and become a true event-driven system? I recall some discussion on that during F10, might want to get Casey Dahlin to weigh in on that.

Harald: upstart-0.5 would be ready for the basic use case of moving essential services from SysVInit style to upstart and start them in parallel.

[edit] readahead + SSD ?

There have been reports that when using SSD drives, readahead only makes the performance worse (because there's 0 seek time with SSD drives). There should probably be an option to disable readahead easily -- or even automatically. Ksvist 23:52, 24 March 2009 (UTC)
