I have been using DSpace for over a year now -- 1.3.x and 1.4.x -- on
Solaris 10 with Sun's Java System Web Server (6.1 and 7.0). I use
DSpace for Indica et Buddhica - Repositorium: a digital archive
designed to capture, store, index, preserve, and distribute materials
pertinent to Indology and South Asian Buddhology. While the aim is to
build an archive that enables Indologists and Buddhologists to
catalogue and store a variety of materials -- articles, books, images,
theses, software, working papers and so on -- the main concern at
present is to lay the foundation by filling the archive with relevant
bibliographical records. This is underway and almost 25,000 records are
available already, the same number again should be loaded within the
next few weeks. More details here:

You are at the critical stage of selecting and assessing an archival
platform so I will try to address your concerns candidly.

I am currently using DSpace only as -- for me -- there is presently no
suitable alternative. While I was impressed by proven scalability of
Fedora, the lack of a decent Java web app. admin. and user interface
ruled it out. (I prefer to avoid PHP apps if possible,  and last time I
tried Fez it consistently crashed Sun's Web Server -- completely
unacceptable on a test server, let alone in production.) Another suite
capable of scaling was CDS Invenio (a.k.a. CDSWare). Unfortunately it
is rather complex to compile, configure and maintain on Solaris so is
not currently an option. Unfortunately, all that is really left is
DSpace, with its well known performance and scalability issues.

Although these shortcomings have been raised many times on the mailing
lists I seen no evidence that they are being addressed with anything
but lip service. The discouraging findings of this technical
evaluation, I believe, still hold:

>From my own perspective, then, I see DSpace as nothing but a temporary
solution until a good Java web app. is developed for Fedora. Another
alternative, perhaps more likely in the short term, is Nuxeo's soon to
be released Java app. Nuxeo 5. I am already using their Zope based CPS
4 for the front end of my site and very happy with it. Nuxeo claims
that CPS 4 has been tested and approved with more than 3TB of live data
(3 million documents). It is intended that version 5 will effortlessly
scale to over 5TB. This will need to be assessed, but early indications
are convincing. Below are a few references. You may like to note that
their current development is being driven by the needs of clients
perhaps not so very different from your own:
