Why is LINQ problematic in real-time event processing systems?

LINQ introduces latency and allocation overhead unsuitable for real-time event processing.

Real-time systems require deterministic execution and minimal latency. LINQ adds iterator chaining, delegate calls, and potential heap allocations. These introduce jitter and GC pauses, making LINQ unsuitable for high-frequency event streams. Event-driven architectures often use streaming frameworks instead of LINQ pipelines.
