Just because a query uses an index does not mean it is going to be fast. The statement may need tuned, the index may be a bad index to use, or depending on the amount of data you will be retrieving indexes may not be the way to go. The power of the machine will also have an impact.

There are a lot of things that you will need to look at. If you get a little more specific it would be easier to help
