After becoming almost irrelevant, RAM is again becoming a very critical
commodity. In the case of single machines, saving a couple of bytes ram was
pretty much absurd, especially with enough swap, the affect would only be
temporary, and there wasn't any real price difference between a 52MB system and
a 512MB system. But with virtualization, 32MB means you can have 10 times the
number of virtual machines, and the price actually goes down 1/10th.
ONce virtualization picks up, memory optimized systems are going to make a
come back. And it seems to be an entirely new market, since all mainstream
applications seems to have given up on memory optimization. For instance, the
three of the most popular applicatins: bind, spamassassin, apache are all
memory hogs, using memory unncessarily. I mean, why the heck do you need 200MB
for running a web server? That's quite insane.
