	I was site manager at a site with a few 3620's a year or two ago.  We found
	that the apparent speed of a 3620 also depends a 1lot0 on the amount of physical
	memory you have on them.  There's a threshold below which they're so slow as to
	be almost unusable.  Above that threshold, though, they worked well for us.

    What's the threshold?  We have 1.5 megawords on ours at the moment.  And
    I wonder what the "threshold" on the MacIvory is?

I had similar problems (?) with the 3620.  I now use 4 Megawords on our
3620, and it's faster than a 3640.  I found that anything less than 2
MW results in horrible performance.  I didn't notice any "significant"
improvement in performance once I passed 2.5Mw.
