Pull request overview
This PR optimizes the performance of the EqualsIndexer by reducing the HashMap load factor from the default 0.75 to 0.5, which improves lookup speed at the cost of slightly increased memory consumption. The change is based on experimental benchmarking on index-heavy problems and includes comprehensive documentation explaining the rationale.
- Decreased HashMap load factor from default (0.75) to 0.5 for improved lookup performance
- Added detailed documentation explaining the choice of initial capacity (16) and load factor (0.5)
- Documented the trade-offs between memory consumption and performance
