Make the Calculations Faster

The calculations can slow down a lot on medium to larger builds.

This is a very hard problem to tackle and it is not caused by a simple bug but rather requires the design of a more efficient algorithm or complex optimizations to try and simplify the problem. This has been worked on greatly since 2022 to even get it to where it is today and hopefully more improvements can be made.

There is also the manual calculator which does not take into account how splitters and mergers prefer to split/merge and is always fast.
