Point of which to break out Projects from ProjectSuite ?

I have a ProjectSuite, with four Projects within.  (due to one App with 4 parts to it.)



The first 2 projects have a lot of framework code along with 367, 180 test scripts

respectively for these first 2 projects.  The last 2 projects are not developed out.



I have noticed as time has gone by from initial development and script creation, when running a script or test code it takes a lot longer now than before.



I use JScript as my coding standard.



I know there is a lot of framework and script code that TestComplete is keeping up with here for me and compiled at the same time.



I am looking at finally breaking the 1st project out and making it independent.



I did think ahead for this ProjectSuite and there are no dependencies between any of the project.  I was trying to keep all code together for same application.



Anyone experience this before, or done the following to separate a project out?
