Use of transformers Performance Issue


Using Transformers in a flow service for string concat, addInts etc. will affect performance of the service? Please let me know when and why to use transformers and when and why not to use them.

Thanks in advance,

What version of IS are you using? The pipeline management of transformers changed in 6.x.

The “GEAR 6 Performance Tuning White Paper.pdf” doc has some information on performance tuning.

There are a few threads on this forum. Search for “transformer performance.”

Of course, you’ll want to keep the 3 rules of optimization in mind:

  1. Don’t optimize yet.
  2. Don’t optimize yet.
  3. Don’t optimize yet.

Optimize only after profiling has revealed the bottlenecks that will provide the performance boost needed without compromising the solution design.
