Optimizing expressions

Optimizing expressions

You can optimize the expressions used in transformations. When possible, isolate slow expressions and simplify them.
Complete the following tasks to isolate the slow expressions:
  1. Remove the expressions one-by-one from the mapping.
  2. Run the mapping to determine the time it takes to run the mapping without the transformation. If there is a significant difference in mapping run time, look for ways to optimize the slow expression.
