[BUG] Slow reaction time when running tests

[DanielPenning]

Describe the bug Starting a test within RobotCode adds around 3s overhead compared to running the same .robot file from the CLI with robot. For short development loops this overhead is disturbing.

To Reproduce Steps to reproduce the behavior:

1. Add a new file empty.robot in an otherwise empty directory.

   *** Test Cases ***
   First
   No Operation

2. Run the suite or test by ckicking on the green icon left to it.

Expected behavior The command should execute the tests with almost the same speed than running the CLI. But:

• CLI: robot empty.robot takes around 500ms
• The IDE action takes around 3500ms (so a 3s overhead)

Desktop (please complete the following information):

• VS Code Version: 1.91.1
• RobotCode Version: v0.83.3
• OS: Windows 10
• Python Version: 3.10.6
• RobotFramework Version: Robot Framework 7.0.1 (Python 3.10.6 on win32)
• No other plugins installed in VS Code (clean profile). Default user settings.

How is this noticeable? When I press the Run button, a new terminal opens, if one is not already open, and it starts within 1 second. Where are the 3 seconds lost? And how do you measure that? What is the start and what is the end point? Maybe you record a short video clip to show it?

You have to bear in mind that it can't be quite as fast as on the console, as VSCode also has to connect to the test run, a new terminal may be opened, etc.

Sorry for the late response. I created a short video. I measured this in a simple way: Manually with a stop watch.

The video shows about 2.5-3s delay - so this is a bit better than originally written above. The video was made with a bit more recent versions (VS Code 1.92.2, RobotCode v0.87.0).

@d-biehl Is this helpful for you to reproduce?
