Akshat Aranya created SPARK-7795: ------------------------------------ Summary: Speed up task serialization in standalone mode Key: SPARK-7795 URL: https://issues.apache.org/jira/browse/SPARK-7795 Project: Spark Issue Type: Improvement Components: Spark Core Affects Versions: 1.3.1 Reporter: Akshat Aranya
My experiments with scheduling very short tasks in standalone cluster mode indicated that a significant amount of time was being spent in scheduling the tasks (>500ms for 256 tasks). I found that most of the time was being spent in creating a new instance of serializer for each task. Changing this to just one serializer brought down the scheduling time to 8ms. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
