- Acorn Computers in the UK (who came up with the ARM processor) had a
- port of bsd4.3 which did this on executables. You 'squeezed' the
- executable and each time it was run, the loader noticed and unsqueezed it.
-
- How do you use the 'compress' feature on DOMAIN/OS? I come from the
- Unix side of the universe and don't use 'typeing features of the
- filesystem.
-
- For what it's worth:
-
- * I think the typed filesystem is a nice feature
- but you pay for it with desparately slow reading and writing from
- disk. I have here a 2500 with a 760Mb SCSI drive. It's disk operations
- are 5x slower than a PC running Interacive SVR3.2. Personally, I'd
- rather have 5x faster disk and do the work in my own program.
-
- * The inability to reserve an amount of disk to be used by the
- operating system for paging is painful. User cheerfully fill up the
- disks and then wonder why their systems go to sleep. /dev/swap
- anytime.
-
-
- * Networked filesystem is wonderful. And the lack of YP/NIS.
