update is not slow with bitmap index

2 min may not seem big improvement.
BTW, i was asking to test with a table with millions of records not with millions looping update.
The reason why you should not compare the result
1. If Table got less amount of data
2. The table has only 3 columns,Only 3 columns, that means less space for physical storage. If you simulate with some kind of real time table, i think you'll able to gain more time.
