Summary: Anybody using it?  Is it worth having?

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.
