When do you optimize the excavator by 6-8%?
When we put in all of popular algorithms and get some good anti-reversing tehcniques in place so our ideas and hard work isn't stolen again. Until then, we better keep it a bit under, so we don't draw too much attention.
Your kernel is slow. You stole the idea from the silent army..
I based it off Tromp's solver, which was under MIT. Some parts of the code (indices dup checking and sorting) is from SA (again MIT), besides that, I didn't even read SA kernel. We can't say the same about your endeavours eh? Sell this GPL closed source, sell that GPL closed source...
