Progress

• Landed bug 499123 on the 1.9.2 branch.
• Bug 475289 landed on trunk for a ~20ms improvement with the currently shipped plugin set.
• Reduced the number of getService calls in the microsummary service.
• Wrote a patch to get the search service using the new update-timer category, removing one of the last few pieces of non-critical work the search service does on startup.

Next Steps

• Need bug 520334 to avoid losing the benefits of 475289 once we ship a plugin with an update URL.
• Work on delaying spell check dictionary initialization in bug 496217.
