描述

Groupie makes a lot of requests to methods like getIndex(Item) which internally iterate through all the children of a group. In practice, this is rarely problematic, but it could become an issue with very deeply nested groups and items at the end of extremely long lists.

研究方向
Start by profiling the getIndex(Item) method to measure its performance impact with deeply nested groups. Look at the Groupie source code, specifically the Group and Item classes, to understand the current iteration logic. Consider implementing a HashMap based lookup to avoid linear scans, and evaluate memory overhead. Review existing comments in the issue for any prior suggestions. No linked PRs or maintainer clarification needed.
