Database
Early benchmarks suggest you need about twice as
much processing power to run a relational database on
HP-UX than to run IMAGE on MPE/iX.
For example, if IMAGE calls are consuming 40%
of the CPU cycles on your 500MHz MPE/iX system,
plan on THAT PART of your processing doubling.
So you need to add the equivalent of another 40%
of 500MHz, or 200MHz more.
Early adopters strongly advise customers to get a data
base administrator who knows how to tune the chosen
relational database environment.
