Tabl e 1 . List of evaluated configurations. Note that each one was executed twice and
the average is reported. Each configuration was evaluated using 3 strategies: no cache,
any partition and only local partitions.

3.3 Computing Infrastructure
HBASE version 0.94 run in Ubuntu 10.04 server with Intel® Xeon®. The work-
ers process were scheduled in TORQUE, a distributed resource manager that
provides control over batch jobs over five virtualized compute nodes managed
by OpenNebula (http://opennebula.org/). All nodes and the HBASE server run
the Java Virtual Machine 1.6 version, each node with dual quad core processor
and 64 GB of RAM. This is shown in Figure 3
