zhztheplayer opened a new issue, #6074: URL: https://github.com/apache/incubator-gluten/issues/6074
### Backend VL (Velox) ### Bug description In some cases when runtime filter is added, `spark.gluten.sql.columnar.backend.velox.IOThreads=0` (which turns Velox's preload / prefetch off) could gain better performance than the default settings (`spark.gluten.sql.columnar.backend.velox.IOThreads=<task slot num>). Caused by https://github.com/facebookincubator/velox/issues/10173 To temporarily by pass the issue if found, just set `spark.gluten.sql.columnar.backend.velox.IOThreads=0`. ### Spark version None ### Spark configurations _No response_ ### System information _No response_ ### Relevant logs _No response_ -- This is an automated message from the Apache Git Service.
