two questions

you want to update every single article to category 1? why? and where in the world did you find time to write nine million articles?

also, why do you feel you need to do it in increments?

i don't think i can help you any more

you want to artificially "relate" articles by assigning them randomly in blocks of 100,000

sounds like you're trying to solve one problem (poor performance) by creating another (relating articles into categories based on their id number or something)

you still didn't answer my question about where you came up with that many articles in the first place, but don't bother, because i don't think i'm gonna like the answer
