What platform would you recommend for building an authority website or a large website. I use WP but I have noticed that after 3000 or so posts the database starts slowing down. With google indicating that one of the key factors for ranking going forwward would be the site load speed, WP will struggle to load fast when your database gets too big even with plugs in like super cache and minify, I have even tried CDN's.
Also I have noticed all my sites which are hybrids static and wp platform tends to do well. Has someone had any experience?
Can someone share some thoughts and give me some recommendations pls?
