If I may advise you, try to get the execution plan of this query and some statistics.
The simplier way would be connecting to the database via SQL*Plus, setting autotrace on (SQL*Plus 3.3 or above) and executing your query. After performing that you should get the execution plan and statistics. This info may point out what the problem is.
