I've been passed some preliminary documentation on an AT&T product called
TUNEX, a ``UNIX OS Performance Tuning Tool.'' It uses data from sar, sadp,
acctcom and mount in order to come up with the following advice to a system
administrator:
-- effect on performance of choice of disk cache size
-- when a dcopy is advisable to optimise accesses to particular
filesystems
-- how best to allocate different filesystems to disk drives
-- suggested sizes for various system tables
-- places where setting the sticky bit would be a good idea.
As AT&T UNIX Europe does not yet have full product information, I wondered
if anybody out there could help me with these questions:
1. Is it out in the field?
2. Is it worth having (we have a 3B2/400)?
3. Is it specific to 3B series systems (or alternatively, is it available
in source form, for example through the Toolkit set-up)?
Thanks.
