I have just committed optimized code to help this policy achieving high scheduling quality and meanwhile ensuring high performance with cache enabled. There are 2 important improvements: - Introduce PreferredIterator with next-fit policy to avoid always choosing the first node when cache enabled. - Separate sorted nodes to 3 zones: preferred, normal and ignored to achieve high scheduling quality, front nodes in preferred zone will have more opportunities to be chosen then nodes in normal zone, and rear nodes in ignored zone can be ignored in the scheduling process for now to avoid make things worse. -- This is an automated message from the Apache Git Service.
