Sage startup is slow (especially on high-latency file systems like NFS) because thousands of individual files have to be read when the import tree is evaluated starting at sage.all. Splitting up large files into multiple small ones like in your patch is great for code maintainability but hurts startup time. Especially if you refactor code you should switch to lazy imports if possible.
