- Replaced LINQ `.Sum()` in `NetworkSimulationEngine.AnalyzeContextResults` with manual loops. - Replaced LINQ `.Any()` in `TemporalNetworkSimulationEngine.IsWithinAnyWindow` with a standard `for` loop. - Reduces enumerator and delegate closure allocation overhead in hot paths to relieve GC pressure.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |
💡 What: Replaced LINQ
.Sum()calls inNetworkSimulationEngineand a.Any()call inTemporalNetworkSimulationEnginewith standardforeachandforloops.🎯 Why: In high-frequency hot paths within the C# simulation engine (such as result analysis and per-period active window checks), LINQ extension methods create hidden interface-based enumerators and delegate closure allocations. This leads to continuous, unnecessary garbage collection pressure and CPU overhead during heavy simulation runs.
📊 Impact: Reduces GC pressure and heap allocations significantly during tight loop executions by avoiding
IEnumerable<T>instantiation and delegate invocation per element.🔬 Measurement: Code cleanly passes all existing unit tests. Run
