FastFileFinder Now 30 Percent Faster—How Fast Can You Make It?

A while ago I whipped up a small utility to search for filenames at the command line. I noticed recently that it did not handle long filenames over 260 (MAX_PATH) characters. Having a few spare minutes I updated FastFileFinder to use the Win32 API directly as the .NET Framework Directory methods do not have that support. Additionally, I took at idea from Josh Carroll and batched up the matching filename output to minimize the calls to Console.WriteLine.

With that little bit of work FastFileFinder is now 30%-50% faster! I haven’t looked too much harder but I think there’s some more speed up work that can be done. Are you up for the challenge? How much faster can you make it go?
