- Reduced memory usage from 895 MB to 420 MB in a Rust program by optimizing struct layouts and JSON deserialization.
- Used `Option<Box<BigStruct>>` to store optional structs on the heap, leveraging niche optimizations to reduce memory when fields are `None`.
- Benchmarked memory improvements using jemalloc with custom profiling features to verify the impact of the changes.
