Hi,
My original question:
>Hi,

> My main interest is maxusers. What is the default amount?

> How much memory is allocated for each additional user?
>
> Basically, we consistently have 40+ people logged in, and am curious
>if I need to tune this a tad (along with any other kernel variables).

SUMMARY:
I was told by several people to check out the book Sun performance Tuning by
Adrian Cockroft. Info on this book can be found at http://www.sun.com/smi/
ssoftpress/books/Cockcroft/Cockcroft.html
I was also told that sunworld archives are online...http://www.sun.com/
sunworldonline. Adrian Cockroft has a column here which often discusses
kernel tuning.
As far as default values on Solaris 2.4...I was told that maxusers defaults
to 40 by a couple people, but most say that it is dynamically allocated
based on the amount of RAM. Most people said that maxusers=Meg of RAM - 1.
One note that many people wanted to be sure that I knew (and I do :) is that
maxusers is not really the maximum number of users that a system has. It
is a variable which othe kernel uses in many different ways.
We do have "pt_cnt" set to a higher value to allow for greater simultaneous
connects.
Thanks to...
