# Fast Coster

A business costing system that is super fast:

- Money movements in less than a second
- Overhead allocation in ~2s for large datasets (~10000 departments) and not flushing every from record - up to 10s when flushing from/to allocations

## General Notes

Setting the number of threads in overhead allocation: set RAYON_NUM_THREADS environment variable ([doc](https://github.com/rayon-rs/rayon/blob/master/FAQ.md)).
Note multithreading is only currently used to calculate allocation percentages, it is not used in the main allocation processing.
