- Actually, you could well be right. But seeing as you have come to a correct
- conclusion using entirely the wrong reasoning, you still don't get any points!
- (At least that's how it used to work back in my University days! :-))
-
- A tuppeny check of a couple of Windows clients around this local would
- indicate the "average" Windows client holds about 7 or 8 files open
- even when it's doing nothing. One might extrapolate that 250 such clients
- running Windows from a server may well hold a little under 2000 files
- open on the server. Well, indeed they do but, if things have been setup
- by a non-amateur, the 7 or 8 files held open by each client will be largely
- the same ones. Thus no directory cache thrashing will be incured.
-
- So my wrecklessly-typed-with-no-thought example was indeed flawed. So what
- is the directory cache optimised for? Errrr.... abuse! That's what.
