The defaults seem to be fine for most people.  They're larger on S10
than in earlier releases.  The S10 defaults aren't as large as the
/etc/system settings shown in the SRSS docs but there's a fair bit of
headroom in those settings.  See the S10 Tunables Guide, specifically
<http://docs.sun.com/app/docs/doc/817-0404/6mg74vs95?l=en&a=view&q=shm>,
for details.

You'll see that the old tunables have been converted into project
resources and are adjustable at any time.  There's no longer a
need to edit /etc/system and reboot if you want to change them.
This is why it's far less important to boost these settings at SRSS
install time; there's no longer a reboot penalty if you find that you
need to adjust them after the system is up.  And you can have the
system tell you ('rctladm' can enable reporting to syslog) when a
resource is exhausted, so you don't have to guess whether the
system has hit a limit.
