For informational sites, I would not expect stable traffic too fast. In the first months Google still needs to understand the site its structure, authority and whether people actually find answers there. My new site started showing real results only after about 6 months and noticeable traffic came closer to one year.
But separate low-competition pages on my car blog can start getting traffic from Google in 3–7 days. More competitive pages usually need 1–3 months. If it is a service site in a small GEO, results can come faster, sometimes in days or weeks.
What helped me most was not just publishing more pages, but building a tight structure: internal links, clear clusters, fast loading and normal navigation.
