How big is performance cost of "project in project"

[azp]

As in tittle
Lets say i want to use 100 threads of the same template.
I have option either have complete template, or make template that will use 2-4 "project in project" properties.
Will it impact performance if i use many "project in project" or it does not matter ?

Go for it. Cost is really low. It compiles only when it's needed and only one time while ZennoPoster is running. All other times it use compiled code unless it's changed. My biggest money project is all about project in project actions
