Use of transformers Performance Issue

[snehalsm]

Hi,

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,
Snehal.

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.

Hello,

You may want to use a transformer to hold a list of services to execute for which the order does not matter. The execution is not parallel, so don’t use it thinking you can execute concurrently. You may also want to use it to easily have an automatic scope of passed in and passed out fields. Other reasons nay or yay are really along the lines of optimizing and Rob already made the point. Good day.
