Forums / Cotonti / Support / Can Cotonti handle >1000k pages?

The largest Cotonti site that I have some statistics about has ~40k pages in ~500 categories, ~140k registered users, ~330k forum posts and ~ 4700k database records overall. Most other systems would require much more efforts to run such a big and popular site.

There are some server-side optimization tricks apart from those mentioned by GHengeveld. For instance, on huge databases it is recommended to convert MyISAM tables to InnoDB, because InnoDB doesn't crash in such conditions despite it's a bit slower than MyISAM. There's also static page cache feature which can output index/pages/forums almost at a speed of static pages.

I recommend starting with a normal setup and optimizing it as your database/userbase grows.
