Advanced SQL Performance Tuning

  1. Reduce data request: proper data types and compress set up and proper index utilization.
  2. CPU: Avoid sorting and whole table scan.
  3. Reduce data returns: only return data that are needed to reduce Disk IO and Internet IO.
  4. Reduce interactions: DML sets and stored procedures help reduce DB connection times.
