most of these shm & ipc parameters are dynamic in Solaris 10. The defaults for 
Solaris 8 & 9 were ridiculously small! shminfo_shmmax is the the largest single 
shared memory segment that can be created, generally just set this to physical 
memory (if an app wants more than this, or it just can't be provided the app 
will just not run)

Large shared memory segments are most often used for database applications and 
are specified within the app.  I don't believe Networker itself requires large 
amount of shared memory, though it can't hurt to change params to more 
reasonable settings...

Of course memory tuning, filesystem tuning etc will benefit performance, 
however from ny experience the biggest gains are to be had with multiple data 
streams. Get the server working hard to load that fibre!
