Best way to do regexp search on file directory?

Hi,

I was wondering if anyone has any suggestions on how to do an efficient regexp search on a list of filenames (12000+) straight from a local physical directory?

The current method I am using is pulling up the directory in a File object and doing a wildcard filter on a subset of the files. Then taking this subset of files and doing the regexp matching on this short list. However, I find the I/O times to pull up the list of files everytime to be a bit too slow for our particular application.

any suggestions on how to improve this search?

Thanks!
