## Summary Based on the performance analysis in the spike issue [#534953](https://gitlab.com/gitlab-org/gitlab/-/issues/534953), we've determined that Rapid Diffs ~frontend can handle significantly more files and lines than current limits allow. The current bottleneck appears to be on the ~backend rather than frontend rendering. ## Goal Increase the diff limits for Rapid Diffs to improve the user experience while maintaining acceptable performance. Performance testing showed: 1. Rapid Diffs significantly outperform legacy diffs at all file sizes 2. Frontend remains responsive with expanded diffs up to ~600 files × 400 lines before GDK issues occurred ## Risks 1. Increased server-side resource usage for large diffs 2. Impact on Gitaly performance with larger diff sizes? ## Related Issues and MRs - Spike: [Refine diff limits for Rapid Diffs](https://gitlab.com/gitlab-org/gitlab/-/issues/534953) - Related MR: [Use content-visibility on Rapid Diffs files](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/186036)
