Pub workspace analysis takes 18 minutes to complete

[FMorschel]

Here is the profile https://drive.proton.me/urls/GTYVJYYNN8#lZgO6qUFvmp1, it is quite big 😅 (over 1.5 GB).

I have a private pub workspace that, when you open it whole (or run dart analyze), takes 18 minutes to complete. I recently found out my AV was slowing down any dart.exe runs, so I'll also measure things again now without it doing so.

@mraleph suggested:

if you have any place where you can upload it - we could try to figure out ways to slice/analyze them in batch mode rather then to try viewing them in UI.

What's the total number of LOCs in this workspace?

Were you able to do this? IIRC, some of your disk access was up to 10x slower with our tests scripts, so it may be better to debug without this (it might avoid looking in the wrong place).

Was this project the same one that led to #62539? That issue isn't resolved yet, so if this project is one with nested analysis_options includes, I suspect that's probably a large part of the issue (one way to check this would be to drop the includes for third-party analysis options from your "shared" analysis options and see whether that makes a significant difference).

I've used: (Get-ChildItem -Recurse -Filter *.dart | Get-Content | Measure-Object -Line).Lines to count them up. The result was: 175,291.

Not yet, but I'll probably be able to do it today. Though the 10x is not the correct number against my machine, it was the correct number against yours. My machine was 3x slower than yours, even without the AV.

Yes, it is.

I'll do that later and let you know. Thanks for the idea!
