system and application performance are degraded with HP-UX 11i as compared to
HP-UX 11.0. In fact, performance with HP-UX 11i is generally better than HP-UX 11.0

While not recommended, one of the options for installing HP-UX 11i is as a base
operating system only, without an Operating Environment. Installing HP-UX 11i as a
base operating system will give the greatest performance and the lowest system
overhead but eliminates the advantages provided by the HP-UX 11i Operating
Environments.
