[rescue] sparc10 cpu - what to do.

now that my memory is prodded, i have a little sunos kernel tuner shell
script i wrote according to an old sun performance overview article.
sunos came out when memory was expensive and most machines had what
we'd consider really tiny amounts of ram; only really bulky machines
like db servers et al had anything like what we'd consider normal now.
the sunos kernel was optimized for memory in the single-digits of MB.
the script calculates and resets several variables in either kmem,
vmunix, or both.  it can be run on a running machine.  i don't know if
you'll get a perceptible, or even measurable, speedup.

i also have a ksh function which assists in calculating disk partition
tables for the cylinder-boundary metaphor, still needed as late as s8
but really obsolete in the zbr era.  have late-model solarii given up 
on it yet?

anyone interested in them?
