Loop parameters operator slows down

Loop parameters operator slows down

I use rapidMiner 5.3 in which I have a workflow in which I use the 'Loop Attributes' operator. In the operator, I use the same operators on the same data. It seems to me that for every run the execution time of the the same operator is slowing down although I use the same data and the same parameters (only a different seed).

Has anybody experienced the same problem and knows how to solve it?

Re: Loop parameters operator slows down

Have you tried dropping the Free Memory operator in parts of the process?  It might help a little.

Yes, I have already done this. This did not solve the problem.

Re: Loop parameters operator slows down

You could try to add a Materialize Data operator as first operator inside of the loop. In some constellations this can prevent the performance loss as the iterations proceed.
