This is just out of curiosity. What is the performance of your board?
To get started:
$this->bbcode_second_pass_code('', 'pacman -Sy base-devel wget
cd ~
wget https://byte-unixbench.googlecode.com/files/UnixBench5.1.3.tgz
tar xzf UnixBench5.1.3.tgz
cd UnixBench
make
./Run -c X')
where X is number of cores on your board. big.LITTLE 8 core arm architecture only allows for 4 cores to be used at a time.
Results from devices that I have:
Something to compate to, an older x86 chip (quad): i5-750 @ 3.1Ghz
