Link Time Optimization

Link Time Optimization (LTO) is a process used during software development that improves the final program's performance and size. When software is compiled, individual parts are created separately. LTO merges these parts later in the process, allowing the compiler to analyze and optimize the entire program as a whole — such as removing unnecessary code or better organizing data. This results in faster, smaller, and more efficient software. Think of it like finishing touches on a puzzle: seeing the entire picture helps you arrange pieces more effectively for the best overall result.
