[I] [VL] Slow scan with Spark runtime filter when split-preloading is turned on [incubator-gluten]

["zhztheplayer (via GitHub)" <gi...@apache.org>]

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`.
