How do I optimize my usage of oclvanitygen?
1) Make sure the Vanitygen you use has the AMD patch (if you have an AMD GPU, Vanitygen Plus has it)

2) Update your GPU drivers (can't be done on Mac)

3) Play with each of these constants. Their effect is different among the GPUs and drivers, and you may never know if they can have a (relatively) significant positive effect performance.
