You might try obtaining a few rather large traces and running bro 
against those traces with '-r'.  Record how long it takes to process 
these traces both without the changes you've made and with the changes 
you've made.  The difference in these two times might give you a rough 
idea of how your modifications impact bro's performance (given observed 
traffic similar to that of the analyzed trace).
