Workbench is very slow after several projects are created/imported

The problem appears during the Default test scenarios test session of Business central High Availability.

After creating several projects / importing several samples, workbench become very slow.

List of the problems we saw:

• the projects are indexed and compiled which take more then 10 minutes.
• after that it is very slow to open a space ~2 minutes.
• after that it is very slow to open a project >5 minutes.
• after that it is very slow to open an asset >5 minutes.

Workbench become unusable for regular work. Loading popups are visible during opening spaces/projects/assets also when you edit an asset, you can be disturbed by the Loading popup.
