I know very little about this derivative and i have no idea about its strength. Just let me share what Alexei has compiled for Android devices. Thanks again.
A short script by the author Jose Perez taken from a very old forum post says:
"I must THANK those who are helping me to the project by testing the engine derived from SF and using it in different game servers, that I am only learning and that every day I hope to increase the strength to the engine and the speed / agility of search and to find an optimum point . I just started, I hope you do not demand that I be the number 1, it's just the beginning. Thank you."

I assume the never build was made for improvement only, from the same source code.
