And, if you’re still stuck at the end, we’re happy to hop on a call to see how we can help out.

`DebugService` has high cost

See original GitHub issue

Profile startup/reload (w/ simple text editor, just the explorer visible)
Drill into code editor creation
Notice that ~30% its creation time is spend in the CallStackEditorContribution contribution

That itself is cheap but it “force creates” the delay/lazy debug service which causes a ripple of events and other things. It would be better if we can keep this lazy and depend on the service to soon

It would be cool if simply listening to an event would not instantiate the service, but would return a proxy event emitter that would be hooked up to the real thing when the service gets instantiated for some other reason

Love it. @alexdima and I had discussed the same thing yesterday. I’ll give it a try and see how much we can save like that
