I've been doing some testing on both the emulator and using Nexus 4. Testing startup time of Contacts app from unity, the command line, and upstart.
The results can be found here: https://docs.google.com/a/canonical.com/spreadsheet/ccc?key=0As1Fg7XBGWTjdDJ3VHptQUN5RGNnVmpmZTVFLXg2cEE#gid=0 There is a clear performance hit using upstart but not yet clear what exactly is causing the slowdown. Some of the timing suggests that part of it may be chaining upstart jobs and the overhead associated with that. But most likely there are other causes. ** Also affects: upstart-app-launch (Ubuntu) Importance: Undecided Status: New ** Changed in: upstart-app-launch (Ubuntu) Importance: Undecided => High ** Changed in: upstart-app-launch (Ubuntu) Assignee: (unassigned) => Ted Gould (ted) ** Changed in: unity8 (Ubuntu) Importance: Undecided => High ** Summary changed: - Apps Taking Longer to Load + Slow app startup time ** Also affects: unity-mir (Ubuntu) Importance: Undecided Status: New ** Changed in: unity-mir (Ubuntu) Importance: Undecided => High ** Changed in: unity-mir (Ubuntu) Assignee: (unassigned) => Ricardo Mendoza (ricmm) -- You received this bug notification because you are a member of Unity API bugs, which is subscribed to upstart-app-launch in Ubuntu. https://bugs.launchpad.net/bugs/1257076 Title: Slow app startup time Status in “unity-mir” package in Ubuntu: New Status in “unity8” package in Ubuntu: New Status in “upstart-app-launch” package in Ubuntu: New Bug description: Since upgrading to trusty, applications have been taking longer and longer to load. While on the one hand, there is feature work and investigation to do, see: https://blueprints.launchpad.net/ubuntu/+spec/appdev-1311-sdk-apps- performance on the other hand, this is a regression and should be handled via a bug report for that reason.
