I'm thinking about updating a variable [edit: it is a version free variable by the way] on check-in using Dispatch. But I'm wondering if it could signficantly slow down check-in of a large assembly. It seems like it should be a light weight operation but that doesn't mean it is. 

Currently the variable updates only during State Changes (using transition Actions). 

Similarly how much Dispatch is too much?

I'd like to hear if anyone has experience with Dispatch affecting the speed of operations.

Thanks,

Brian
