I'm quite impressed with OpenSolaris. I've used about thirty Linux distros,
and none of them have worked this well for me. However, I've run into a
potential deal-breaker - OpenSolaris uses a truly frightening amount of RAM. I
have 1 gig, which should be enough to run almost any OS. The included GNOME
System Monitor reports that the default GNOME desktop is using 750-850 MB when
idle. GNOME is bloated, but not that bloated! A look at "prstat" shows the
following:
<code> PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP

I may have used Linux for several years now, but I'm still a bit of an idiot
when it comes to this sort of thing. It's unclear to me how much RAM
OpenSolaris is actually using. However, I doubt if the problem is just System
Monitor misreporting page file usage, because, when I hit 100% RAM used, the
system stalls and begins to use swap space.
Does anyone know how to change OpenSolaris's settings for RAM usage? This is
killing me...</code>
