Performance Implications of Parallelism

Wednesday, December 5th, 2012 12:00 PM Central Time

Parallelism is a key factor in the performance of large queries. It allows SQL Server to perform a large operation quickly and yet at other times can appear to hinder performance. It is a complex topic that can often be difficult to troubleshoot and tune. This session will explain the how parallelism works, why it is good, and when it is bad. Some of the key takeaways will be:

  • What are CXPacket waits and should we care about them?
  • How parallel tasks are scheduled
  • How to read a parallel execution plan
  • How developers can tune for parallelism
  • How DBAs can tune for parallelism
