The parameters shown here in no way constitute a complete list of the kernel
parameters needed for every client or server system. The ones described in this
section can directly impact NFS performance on HP-UX 11.0 and 11i systems.
Many applications require other kernel parameter settings for things like maximum
process storage, text and data segment sizes, semaphores, shared memory, etc.
Be sure to check with your software supplier to ensure that you configure the kernel
variables appropriately for your application software.
