You know the feeling of a system failing. We had a tool called the Treasure Hunt Engine. It searched large datasets. As data grew, the engine failed. It was slow. It crashed.
We tried to fix the old code. We used gprof and Valgrind. We found slow spots. We made changes. These changes did not help. The engine still failed.
We looked at the architecture. The language was wrong for high performance. We had memory issues. We rewrote the engine in Rust. This took a lot of time.
The new engine worked.
- Search times dropped over 50%.
- Crashes stopped.
- Memory usage fell.
- CPU cores worked better.
We used perf and allocation counters to verify this.
If you lead a rewrite, remember these lessons.
- Test languages before you start. Rust is hard to learn.
- Involve your stakeholders early. Some people will doubt you.
The rewrite was the right choice. It helps us give quality results.
