My impression is that using [Debugger.jl](https://github.com/JuliaDebug/Debugger.jl) is much faster than [debugging in VS Code](https://www.julia-vscode.org/docs/stable/userguide/debugging/)

Usage:

```nohighlight
import Debugger

Debugger.@enter function_name(parameters)

```

vs

```nohighlight

@enter function_name(parameters)

```

directly in VS Code

My impression is that In VS Code the debugger is slow downed by waiting on variables to be shown in `Variables` on left panel. (maybe not)

In REPL Debugger after @entering the function I can press C to toggle compiled mode and afterwards I can step through the function very rapidly. In VS Code by enabling compiled mode I can not see any significant improvement.
