@pauldoo agreed. My [cached-then-evicted rerank test](https://github.com/apache/lucene/pull/16145#issuecomment-6476254463) shows where it would pay off: ~90% of the major faults were on .vex, which is never prefetched, yet each one woke every confident file. At 58 probes per JVM hot and no latency cost under eviction, those wake-ups were cheap though. Since perf_event_open would still need a fallback for locked-down hosts, I'd keep `getrusage` as the base and treat per-file attribution as a later opt-in. -- This is an automated message from the Apache Git Service.
