for power state concerns you may want to try running turbostat
(available in recent kernels, runs also on older kernels) during the
workload in question.  Capture the results via something like:
cd /home/jbrandeb/linux-2.6.38.2/tools/power/x86/turbostat
make
for i in `seq 1 10` ; do ./turbostat -v sleep 5 >> turbostat.txt 2>&1 ; done
