• Component: Web Inspector
• Status: RESOLVED FIXED

[Devin Rousso]

For small and quickly loading files, it is annoying to see the IndeterminateProgressSpinner briefly appear before being removed almost immediately.

I know I suggested 100ms, but lets try to arrive at this with more data.

What is the average amount of time it takes for the frontend to load an image when inspecting (1) locally and (2) remotely.

Testing with your Mac Retina laptop should good. I can get you an iOS device to test with.

Once we have that average / bucketed histogram we can provide justification for this currently magic value.

This shouldn't be in the patch.

Nit: "The subclasses are" => "Subclasses are"

You can also say in the comment "... by calling removeLoadingIndicator".

Lets make this 100 to match the ChangeLog.
