Is there much overhead involved in using roles?

I have a query that runs about 4 minutes using the schema owner account. The same query runs about 50% longer using a userid that is attached to a role that has read any table rights.

I did an Explain Plan on both, but they are exactly the same. We are running under RBO. The database is 8.1.7.3 running on Sun Solaris.

Thanks for any light anyone can shed on this.
