查询需要优化的表碎片

When the avg_fragmentation_in_percent >30, please rebuild the index (alter index rebuild). If the 5 < avg_fragmentation_in_percent < 30, please reorgnize the index (alter index reorganize)

 

However, as you mentioned that it finished quickly, maybe you can manage it before you run the job each time. Just arrange it as the preparation for you job. Please update statistics each time you want to run the job.
