As a point of reference, an IBM hardware sales rep I worked with a few
years ago told me that he got a lot of sales from Oracle shops that were
running Sun and switched to RS/6000. Basically, for a given workload, it
would take 2x the number of Sun CPUs as RS/6000 CPUs. The difference in
Oracle licensing costs was usually enough to pay for the new hardware in
one year.
