Slow Expression Tags

Ignition

Anywhere we can find some more information on these best practices for expression tags and using scrips in the most efficient way? I’ll basically avoid using continuously running scripts as much as I can. Makes sense to avoid that.

I started my project with the incorrect assumption that I can just use runScripts.

I have reduced the number of runScripts to basically 0. I only have one that gets called conditionally so it’s not running continuously.

But I’m still a little unclear on the expression tags. I suspect my runScripts were slowing them down but not 100% sure and worry that the amount of expression tags I’m using could be causing a slow down.

So, just to be clear, it’s fine to use expressions (without runScripts), but if they do run slow, we increase the thread count.

sorry I didn’t update this thread once my problem was fixed, but there was a runscript that was taking awhile.
the thread count for expression tags was also helpful to know for any future installations that may require a large amount of expressions.

thanks!
