As someone who had to endure the harsh criticisms from the user community 
when SunOS 4.x was _soooo_ much slower than SunOS 3.5 (remember that one?). 
I was forced to work on a 4MB Sun 3/50 and let me tell you it makes you 
think optimization every day! The good news is that Sun learned a lot about 
kernel performance that helped SunOS tremendously. If Dan Walsh ever reads 
this he is the guy that "made it happen" as far as I was concerned (did the 
benchmarks, identified hot spots, called attention to them etc)
