Submitted-by: kim@uts.amdahl.com (Kim E. DeVaughn) Posting-number: Volume 2, Issue 23 Archive-name: dos/fs/ffsfloppy.uu AutoDiskChange is a small program that you run in the background. Every time you change a floppy it will send the appropriate information to FFS to tell it that a disk has changed. This puts FFS on the same level as the normal file system. FFS will allow you to store 4.9% more data on the same floppy. It will also do disk directories quite a bit faster. Disk reads and writes are speeded up a little, but not that much. This is due to hardware limitations. One area where a big difference can be perceived is when doing 2 or more disk transactions simultaneously. If you're saving some data to floppy in DF0: and reading stuff to the RAM disk from DF1:, there will be virtually no slowdown of either the write or read operations. This is in contrast with the old FS. Note that performing two disk operations on the same floopy still results in HORRIBLE performance loss. # This is a shell archive.
