	OK.  Here's a good article; From Byte Vol 11 No. 2 (that's Feb '86 to
you and me), BYTE UK:  Tripdos--The Roots of AmigaDOS, by Dick Pountain, p. 326:

"The only penalties paid, as trade-offs for all the advantages, are that
directory listing and file renaming are slower than in conventional systems,
because there is no single place to go to look for filenames; the whole tree
structure needs to be traversed to find the names.  Metacomco is currently
considering caching the directory structure to alleviate this problem ..."

	Hint, hint, hint, hint, hint, hint, hint.

"... but from my limited experience of the Amiga, it doesn't seem too bad
anyway; it's not much slower than an IBM PC by the time the latter's
disk-access and screen-updating speeds have taken their toll."

	Poor comparison.  Remember, each Mac disk has a file called DeskTop
which holds copies of each files's icon and filename.  If they could do it,
why not the Amiga?  Please?

	You said it, brother.

Flip side,
