May be of interest:
<http://www.phoronix-test-suite.com/>

It's available in the repository. However for 12.04 Precise I recommend
using the .deb from phoronix:
<http://www.phoronix-test-suite.com/?k=downloads>
<php5-cli>
<http://phoronix-test-suite.com/releases/repo/pts.debian/files/phoronix-test-suite_4.2.0_all.deb>
