Loading Namemapping into memory?

So I'm testing a HTML application that makes extensive use of the Dojo library, as a result there are thousands upon thousands of dynamically created objects. So when I run my tests the first time it takes forever because it's finding the objects. However if I keep the app open and run it a second time it's super fast because all the applicable objects are now in memory.



So my question...is there a way to run through the namemapping first and load the objects into memory ahead of time so that when I run my tests everything executes quickly?
