The savings are due to aggressive caching in the operating system, which cuts the file system out entirely. The disks are slow no matter how you use them. File I/O for things like Python and TeX is slower on Plan 9 because it has to go to the file server, which is in another process or another machine, rather than answer out of a kernel cache like Linux does. Lots of things get easier if you assume you are the only machine in the universe. See earlier discussion on caching read EODs. Russ
