10,000 or more single-page member sites on a multisite network

Hi,

I'm planning to embark a new project using WPMUDEV plugins and wanted to ask for your opinion on whether WP Multisite is the right way to go.

The site will be a social network for businesses, and will feature roughly 10,000 members (each with a single-page member profile).

Do you think WP multisite would be the sensible choice, or would the database become too large to handle?

Thanks,
Burak
