Have you ever changed the garbage collector mode in your system?

Yes, in some projects it was necessary to change the garbage collector mode in .NET to optimize performance. For example, switching from Workstation GC to Server GC to improve performance on multi-processor servers.

This is done through a configuration file or programmatically, for example:

<configuration>
  <runtime>
    <gcServer enabled="true"/>
  </runtime>
</configuration>

Changing the mode helps better utilize resources and reduce pause times during garbage collection, especially in high-load applications.
