The more pages you have, the longer it will take. If you want to speed things up you can do a few things. First get as many incoming links as possible. The higher your link popularity is, the more deeply you will get crawled. Get some links that go to your site map, and any other page that is not indexed. You can also consider submiting to the directories that you are not in. Yahoo, and Dmoz are both good. We have a lot of articles on this type of stuff. You can visit our website too if you like.
