shubhamsrkdev opened a new issue, #15571: URL: https://github.com/apache/lucene/issues/15571
### Description In the discussion in #14156 we found out: Lucene’s `MemorySegmentIndexInput` uses a counter (`consecutivePrefetchHitCount`) to avoid repeated calls to `isLoaded() `and `madviseWillNeed()`. However every slice() or clone() resets it. This means prefetch suppression never converges, causing repeated expensive checks on the same underlying memory. This issue tracks whether we should share the counter across slices/clones to make suppression effective. ### Version and environment details _No response_ -- This is an automated message from the Apache Git Service.
