Well, chances are the find process will be I/O-bound while
the grep will be CPU-bound. So you might find it faster
running them as two processes - grep can be evaluating the
regex while find is waiting for more stuff from the disk.
Of course, it is possible that find is multi-threaded or uses
non-blocking I/O (if it's possible to do non-blocking
directory lookups on Linux or Unix). Anyone want to look
at the source?
Later,
Kenn
