Find is about the fastest way. The bottleneck is in the I/O.
There is not much you can do about that beside getting a better
disk subsytem.

The reason it was faster the second time is because your OS had cached
the information.

If the list of entries are fixed or do not change much, you can try
saving them in a file, so subsequent runs do not have to traverse
through the directories again.
