You might find the TC1 runs very slowly. It is because it has several nested loops which emits very verbose Step Execution logs. It requires long seconds to flush the bulky messages into the Log Viewer GUI. If you are an KS Enterprise user, you can toggle the Step Executio logging Off in the _Project Settings \> Execution_ dialog. Even if you do not have the Enterprise license, still you have an option to make it quicker.

Disabling “Smart Wait” may help I actually already had it disabled it as it was giving me other problems previously Katalon Studio would not emit any verbose “Step Execution Log” messages for Keywords. I recommend you to transfer your codes in the Test Cases (Groovy scripts) into the Keywords (Groovy classes). THIS! It was actually a lot easier to implement than I expected. After transferring the while loop into a Keyword, nothing inside the while loop ge… @YoungNgo let me remind you of this issue. I hope the option of toggling Step Execution Log to be available to all KS free version users. @Bailrod wrote to me: > This post might help, because i have a similar performance issue with a json array loop, converted into excel file and logging sooooooo much info that takes a lot of time ! --- _[View the full topic](https://forum.katalon.com/t/looping-and-perform-action-in-a-changing-table/51746)._
