I don't know precisely why (though I have vague suspicions), but it shows up clearly in the timing tests I did with my Integration Toolkit's debug and timing functions. ---

> [@pturmel](#): > > Use an expression binding with `runScript()` that delegates to a project library script function. Avoid (most) script transforms. Thanks for the tips! I just recently started using more scripts (I had usually just stuck to expression bindings before) so this is all good information! Thank you!! ---

> [@Estera\_Cioroch](#): > > all good information! You should check out my Integration Toolkit module. Even if you don't end up using it, there are binding optimization discussions there, and linked, that will help you make performant, efficient systems. There are many things in Ignition that **need** jython scripts, but they can also be a crutch in other cases. > [@Automation Professionals' Integration Toolkit Module](https://forum.inductiveautomation.com/t/automation-professionals-integration-toolkit-module/74934): > > Automation Professionals is pleased to announce the immediately availability of a major upgrade to its free Simulation Aids Integration Toolkit module. The new feature justifying the "major upgrade" language is the implementation of eleven thirty-one new expression functions which use iteration to accomplish complex transforms of datasets and lists, to or from other datasets and lists, applying filtering, ordering, and computed new columns along the way.

If your class has only one method (plus the init), there are chances it shouldn't be a class in the first place ;p What is that class supposed to do, and how do you normally use it ? Or, asked in a broader way: What are you trying to achieve with it ? ---

I want to calculate the cumulative downtime after the Stop signal is connected, and then call the Scirpt to pass in the Stop signal. Clear to zero every morning and evening at 8 o'clock [Previous page](https://forum.inductiveautomation.com/t/where-to-use-the-script-in-label/82182.md?page=1)
