Well now that we are trying new Linux machines from VMware Fusion to Zotac, it’s interesting to see how fast they really are. Phoronix seems like the top hit and their 4.x suite is available as a Debian repository
sudo apt-get install phoronix-test-suite
How easy is that. If you want their latest tests, then you do have to yank it from the network.
They have a dizzying array of tests with phoronix-test-suite --list-tests
and using it is decently simple. Go to openbenchmarking.org and find an interesting test name and then run the command
phoronix-test-suite list-recommended-tests
TESTNAME=povray
phoronix-test-suite default-benchmark $TESTNAME
Hardinfo is another simple and graphical benchmark tool
