Hi Paul,
In my experience, most concurrent triple stores perform fairly
comparably well for queries. However, if you do plan to load a huge
amount of RDF data into your triple, say more than 10 million, then I
would suggest you get a powerful computer first.
A 64-bit computer with >15GB memory should give you some reasonable
performance. And you can also play with some disk partition.
I wrote some notes a while back, benchmarked on Jena TDB:

Hope it can be helpful to you.
cheers,

Hi Paul,
There was a paper comparing query performance presented at SWAT4LS in
Berlin 2010 by Vladimir Mironov (CC'd).
Within HCLS, many triplestores have been used. It depends on the purpose
and your preferences for features. The HCLS KB is in Virtuoso and
Allegrograph. We've also worked with Sesame and OWLIM. NCBO uses Mulgara
for their SPARQL endpoint. The nice thing about many of the triplestores
is that if you decide to use another one, migrating your data isn't much
work so you're not locked in.
Cheers,
Scott

hi paul,
i did a little research on this a little while ago. you should have
plenty of power.
if you're research i hear oracle offers their spatial triple store
for free, running jena on top of a storage system like BigOWLIMis
also quite popular
check out Berlin SPARQL benchmark
(http://www4.wiwiss.fu-berlin.de/bizer/BerlinSPARQLBenchmark/results/V5/index.html)

*Subject:* triple store recommendation
Hi all,
It was fun joining the conference call yesterday; very enlightening.
I'm looking into setting up my own triplestore (for the first
time!). I was wondering if you'd have recommendations on which
storage backend I could use. I'll be deploying the triplestore on an
okay machine (quad intel xeon X5570 with 48GB, 400GB on striped SAS
disks).
Thanks,
Paul
