We had a similar issue last year. Our streams were fine during the day, but evenings were brutal because of sudden traffic spikes. Switching to a system that had built-in monitoring dashboards and limit controls helped a lot. Instead of guessing, we could see exactly when and where performance was dipping.

The best part for us was the alerts — they actually prevented downtime instead of just pointing out problems after the fact.
