I've seen that take 9 hours on Pentium 4 class computers with 100Mbps Internet connections. This literally requires you to fully verify every Bitcoin transaction that has ever taken place. The downside of a decentralized system is that you cannot trust anything and must check everything yourself. When you run the Bitcoin client for the very first time, it will take several hours to sync up to the network. That will add some time to the client's startup time. If you passed the -rescan option, the client will check every transaction in every block to see if it relates to any account in your wallet. (Upgrading the client will help, since newer version of the client will have more recent checkpoints.)

Slow verification is a much more complete verification that can only be done at about 20 blocks per second on hardware like yours.
Fast verification entails checking only that the header is valid. It is "fast verified" up to the most recent checkpoint and then "slow verified" to the current block. Most of the time is spent validating the database to ensure the client has a sensible view of the hash chain. But I have benchmarked the client's startup process. I can't be sure why your client specifically took 15 minutes to start.
