Or to put it another way: swap does not buy you much on Solaris 2,
once you run out of physical mem the machine dives deeply :-)
I've seen two tests where a solaris 2.3 machine running sunlink-x.25
(and the other sunlink-OSI), during stress testing. The sar output shows
freemem and available swap reducing steadily as sessions are
added.... in one case the machine had 96Mb RAM and 500Mb swap. At
death minus one minute there was about 100 pages of memory and 400Mb
of swap with the machine holding up ok, a minute later both were at 0
and the machine seriously ill.
Could have been a reporting bug in sar but the machine definitely took
a nose dive.
For this reason I voted for SunOS 4.1.3 over Solaris 2 on the firewall
I've been building for a client. Solaris 2 has some advantages over
SunOS but gracefully handling out of memory is not one of them.
