Thank you all for giving your opinion!
Technically, is it the web application or the indexer that requires
most of the memory? What data is kept in memory all the time
(even when nobody is searching)? Is the memory usage proportional
to the number of concurrent sessions?
Thanks again,
Pan

Well, as I said at first, it all depends on your definition of what a
memory hog is. Today's hog fits in tomorrow's pocket. We better all
already be used to that.
Also, I don't think for a *minute* that the original developers of
DSpace made a casual choice about their development environment--in
fact, I think they made a responsible choice given the alternatives.
Let's give our colleagues credit that's due. Their choice permits
scaling and fits well for an open-source project. Putting the general
problem of memory bloat in their laps seems pretty angsty to me.
Lastly, dedicating a server to DSpace is a choice, not a necessity. We
as implementors have complete freedom to separate out the database and
storage tiers, and mechanisms exist for scaling Tomcat horizontally as
well. In the other direction, I suspect people are running DSpace on
VMware or xen virtual machines, too.
