There are some major improvements on the WINTEL at 4.2.1.  First of all,
they do raw IO to the disk pools with 256K blocks.  We observed some
significant performance improvements that lead me to believe that up to 50
Windows Server clients could be supported by a 4 way WINTEL if you have
fibre channel disk and tape like Shark and Magstar and there are enough
buses in the WINTEL to spread out the IO.  You will find that the high-end
Wintel server to do this probably costs more than the UNIX server would that
could do it with 2 processors and half the memory.  So, you have to decide.
With the right hardware WINTEL will run well.  Actually, much better than
some competitive products.
