== Software

Jena 2.5.6  <http://jena.sf.net/>
ARQ 2.4     <http://jena.sf.net/ARQ>
TDB 0.5     <http://jena.sf.net/TDB>
Joseki 3.2  <http://www.joseki.org>
Java        1.6.0_02
            Sun Java HotSpot(TM) 64-Bit Server VM (build 1.6.0_02-b05, mixed mode)
OS: RHEL5

TDB configuration:
  None (TDB has no configuration options)

== Hardware

CPU: 4 CPU: AMD Opteron(tm) Processor 280 @1.8GHz
Memory:   10Gbytes

Note: this used non-local disk, using a shared disk array in a data center.  This provides a more realistic set up of enterprise use. It does make it difficult to draw deep conclusions when comparing with different setups using local disk.

Disk: HP EVA8000 running firmware xcsp-6100.

The LUNs are configured as VRAID5, with read cache enabled and write cache in write-back mode.  Two Qlogic fibre-channel ports (2GB speed) connected to an MDS 9140 edge switch each, then an MDS9509 core switch and finally the EVA.
