FYI, some of the biggest CPU consumers are:

ai_manage_cities - 55% of execution time
  military_advisor_choose_build - 27%
  contemplate_new_city - 13%
ai_manage_units - 25% of execution time

these are simple to profile since they're all called in just one place. 
 Together this is 80% of the server runtime.
