- - Increase maximum disk size from 8 MB to something that actually
- requires doubly indirect nodes. There is a negative pressure here
- from the bitmap object--perhaps we need a specialized bitmap that
- doesn't have to be all in-memory at once.
-
- Alternatively, shrink the inode size.
-
- - Add mkdir and ls example user programs.
-
- - Add option to disable buffer cache.
-
- - Get rid of "dump" commands--they're not really useful.
-
- - Sample solution.
+ - Need a better way to measure performance improvement of buffer
+ cache. Some students reported that their system was slower with
+ cache--likely, Bochs doesn't simulate a disk with a realistic
+ speed.
