Search Performance Tuning

`limits.conf` controls critical search parameters: `max_searches_per_cpu`, `max_rt_search_multiplier`, dispatch directory TTL, and subsearch limits.

When users complain about slow searches, the Architect must determine: Is it a search design problem (too broad)? A resource problem (CPU/memory saturation)? Or a concurrency problem (too many searches queued)?
