Unity performance: we take a real-world hotspot using LINQ and per-call allocations and break down why it can become a bottleneck in gameplay loops. Starting from a managed baseline, we build a simple benchmark to measure both runtime and GC allocations, then refactor the same logic using Native Collections and Burst. By comparing both approaches side by side, you’ll see how reducing allocations and moving data to native containers can significantly improve performance—and when it’s actually worth making that change.
