The answeres I recieved were all telling me that pstat -s only shows swap space. However I found
out also that because my swap was so low our machine does not even use the extra 32 MB of RAM we
installed. From what I gather it is best to have at least as much swap as RAM and even better
to have 2xRAM=swap.

Also from Ken the explanation of where some confusion may lie is that under
SunOS 5.x (aka Solaris 2.x) swap -s tells you the amount of swap + RAM.

Also I should have noted that I am indeed running SunOS 4.1.3_U.

Thanks again.
