Optimize Revit Plugin Resource Usage

My existing Revit plug-in runs correctly but its data-processing routines consume far too much memory and CPU, especially on large project files. I need the code profiled, refactored, and re-compiled so it runs leaner while remaining fully compatible with the most recent Revit release (and ideally future minor updates).

Key focus
• Performance: cut code and processor load during data processing; any gains in speed or responsiveness are welcome but secondary.
• New releases: compatibility for new releases from Revit 2024 to 2027

Deliverables
1. Optimised source code with clear comments on every change.
2. Compiled plug-in installer (.msi or .addin + DLL) validated on the current Revit release.

Please confirm prior experience with the Revit API, C#, and performance tuning so we can start right away.
