Well you see dini is very slow. this is what I used to use when my server was early in development. When I would save my systems my server would lag on my my computer for a minute. It takes years for it save when you have mass amounts of data. You'll understand when you have more systems saving with more data. Basically dini is opening the file then closing for each variable where y_ini will keep the file open then close it when all the variables are written that goto that file.
