Oh definitely.  I knew those were horrible numbers.  I'm not the one 
having performance issues, Jon is.  ;-) 

RT is "fast enough" for me and my users on even that dog slow Athlon 
pig.  (GRIN) 

That's why I was posting was to give Jon something to compare to as I 
have never seen any published performance numbers anywhere.  Perhaps 
they're in the WiKi but WiKi-hunting drives me batty... would much 
prefer a real manual to a wiki any day... call me old-fashioned.
