The question was:
>On a standard Unix machine, 10% of the real memory are reserved
>for disks buffering. Is there a way in SunOS to change this
I just received one answer... Thanks to firstname.lastname@example.org
(Steve Hanson - FERMILAB, Batavia, Il.):
SunOS (well, current versions) disk buffers are mmaped. Essentially
the disk buffer space competes with everything else for system memory.
It isn't fixed at 10%. There's really nothing to tune for disk data buffer
space. You can tweak the metadata cache and the name buffer cache.
There is a good paper on that from the '90 or '91 Sun User Group
