wForget opened a new issue, #9611: URL: https://github.com/apache/incubator-gluten/issues/9611
### Description 1. There may be global lock contention when `closer = None` https://github.com/apache/incubator-gluten/blob/42beaac0686bf5e2d67a0d559b3c47c62a88163e/gluten-core/src/main/scala/org/apache/gluten/iterator/IteratorsV1.scala#L42 2. A large number of closer functions being created also seems to affect performance. https://github.com/apache/incubator-gluten/blob/42beaac0686bf5e2d67a0d559b3c47c62a88163e/gluten-core/src/main/scala/org/apache/gluten/iterator/IteratorsV1.scala#L43-L46 ### Gluten version main branch -- This is an automated message from the Apache Git Service.
