When should I use GCC's -pipe option?

Question

The GCC 4.1.2 documentation has this to say about the -pipe option:

-pipe

Use pipes rather than temporary files for communica

Answer 1

Trying this out now, it looks to be moderately faster to build when the source / build destinations are on NFS (linux network). Memory usage is high though. If you never fill the RAM and have source on NFS, seems like a win with -pipe.
