Larry, your stopwatch must not be working right.  :-)

I created 60 files in the root of a floppy, only 6 were *.info files.  It
took Workbench 25.7 seconds to look at all 60 files, determine which ones
were icons, and display their images the first time through.  I ejected the
floppy (to flush out any cached info), re-inserted and double click on its
icon.  This time it took only 6.1 seconds for Workbench to display all the
icons, since it used the list in the .info file and did not have to read the
File Info Blocks of all the non-icon files.  It was consistant - 6 seconds
instead 25 as long as the .info file was up to date.
