- There's no question that caching adds some overhead to disk access. In the
- first case, you might have been accessing a single file sequentially, in
- which case caching isn't going to provide any benefit. In the second case,
- however, you are accessing a lot of different files, so caching the
- directory blocks will make a big difference. (I don't know why the MPW Set
- command would take so much longer.)

- o blew off a
- test or class or work; picking up and cleaning off someone who drinks too
- much and then brings it all back up on themselves; it's always coming to
- someone's resue ie: bailing them out of jail, doing their schoolwork for
- them, etc. "Enabling" can start out small and end up out of control.
- Like the overprotective mother who panics at the slightest scratch or fall
- her child takes and so locks them away to protect the child from themself.
- It isn't always this drastic but sometimes it is.
-
- When I "enable" someone, I take away their opportunity to fail and in
- failing grow and learn from their mistakes. If I'm doing something that
- is destructive to me but you keep bailing me out before I feel any pain or
- any results of my actions, I will never learn not to do those things.
-
- I guess that's my definition. It doesn't mean not caring or not helping -
- it means letting yourself be used as a doormat and as a crutch.
-
- As always, the above is my experience and my opinion. Take what you want
- but be easy with the rest.
