1238104 - Profile startup time and investigate optimizations

Status: RESOLVED DUPLICATE of bug 1527488

(DevTools :: Debugger, defect)

Description

[James Long (:jlongster)]

After bug 1132501, we took a hit on startup and closing time. Here's a list of regressions: http://alertmanager.allizom.org:8080/alerts.html?rev=256e3e81fed77b17ea9158786a349698bb59a6ab&showAll=1&testIndex=0&platIndex=0

In the DAMP tests we did on the try run, it looks like `close` tests took the hardest hit, so I'm not sure if this is as big of a deal as it looks. I'm trying to figure out where to look at the subtests on mozilla-central. It could be that detaching the thread is slow, so closing the devtools took a hard hit, but opening isn't as bad.

Either way, we should probably look at everything that is happening on startup and see if there's anything we can optimize.

I'm not going to have much time on this for the next couple weeks, but I'll keep it in mind.

Not sure why this is in "Developer Tools: Framework". Moving to the debugger component for triage. Although I'm not sure how we can prioritize that now.
