fireAllRules will only fire all the rules that where activated during the insertion phase. So basically when you call it at the end, it will only fire all those rules activated. If you insert a fact that doesn't activate any rule you don't need to call fire all rules.

I have several thousand objects that gets inserted into a statefull knowledge
session as show below:

          for (Item item : itemList)
          {
                session.insert(item);
          }

          session.fireAllRules();


Assuming that all the conditions in the rules only concern with one item at
a time, will there be a big performance difference if I changed the above to
as shown below?

         for (Item item : itemList)
         {
              session.insert(item);
              session.fireAllRules();
         }
