I have used the settings described here previously:-

http://seer.support.veritas.com/docs/183702.htm

And solaris tuning settings in /etc/system from a performance tuning 
guide but they all seem to be a bit dated and i was wondering had anyone 
any more up to date info for performance increasing?

I have just set up a Solaris 9 netbackup 5.0MP5 with an L25 and two LTO2 
drives.  Im only getting 5meg/sec on a backup test but have done no tuning.

With servers getting better ( this is a v240 ) i was wondering were 
there hight /etc/system settings and other tuning parameters for NBU

Any help would be great

Cheers
