What do you think would be the most cost effective way to generate a higher number of Mkeys/s?
1. Optimize software used to generate the vanity address
2. Use GPU rather than CPU
And what's the difference between KVM or OpenVZ VPS's? My impression is that KVM is superior but why?
OpenVZ have lower overhead which leads to higher RAW performance, but AFAIK KVM have more advance features & support to various kernel/OS
