Not a direct answer but I do notice on the Mac that file_search() is slow only on the first call:

IDL> tic & a = file_search('.','*.pro',/nosort) & toc
% Time elapsed: 41.371398 seconds.

IDL> tic & a = file_search('.','*.pro',/nosort) & toc
% Time elapsed: 0.45945001 seconds.

So file_search() was of order 100 times faster on the second call. This is similar to the Unix find command which stores the information of a search to speed up the processing on subsequent calls.
(I included /nosort because that is supposed to speed things up somewhat but it seemed to make little difference on the Mac).

If your recursive search includes a lot of unnecessary directories, then it might be quicker to use a vector of plausible directories in you file_search() call, rather than searching every directory below the specified one. --Wayne
