Performance slows down in a looping sub-process.

Hi Appian,

There is a Process model(A) and within it there is Process model(B) as sub-process.

When executing the process, it works fine with great performance for the first loop. (less than 1 sec)

But for the loops after the frist loop, the process performance slows down massively (more than 13~16 sec, at least 13 times the first loop performance.)  

The preformance of the process slows down massively. And this is a critical problem for us.

What might be the reason for slow down of the performance.

And how could we fix this?

Thank you
