Currently there are only about 10 users active, probably only one using the site at any given moment, and pretty much everything is slow. Yet there is virtually no load on the system; uptime shows it hovering around 0.2. So at this point it isn't that the system is overloaded; as far as we can tell, it's just that everything is running slowly because it's all running out of swap.
I have advised them to get the system up to at least 4 GB of RAM and see how we do then. More tuning may be needed at that point, but right now it's impossible to tell.
Al, you may be right that the system is underpowered, but furfly has a pretty busy Oracle-based ACS site on a dual Pentium with excellent performance, so you never know. Each installation seems to be different as far as how much load it puts on a system. I have mentioned to Lars that the system might not scale, but I think it's ok to take a wait and see approach for now.
