Take your own advice and compare algorithms to algorithms.  A slow and stupid
algorithm is always going to be slow.  Period.  Thus a faster alogorithm is...
yep, faster.  For example, the Finder uses the Resource Manager to manage
icons, etc, in the desktop file.  That worked OK with 400K MFS floppies.  But
the Resource Manager was never intended to handle the thousands of resources a
100 Meg hard drive can have.  AppleShare replaces this with a B-tree (K?) and
is much faster.

Speed has almost *nothing* to do with the language used!  Most algorithms are
not the ultimate, optimal, fastest, etc.  Especially if the software evolved
over time (and boy has the Finder evolved!).

A hand saw beats a lumber mill any day, if all you want to do is cut a 2x4.
