It seems that you will create a seperate post for each language of the post to be translated. The multilanguage posts are just normal post and all data are stored in the local server database. Is that correct?
If that is the case, then there will be no performance issue since the multilanguage posts just work like the original post.
In the past, we use GTranslate, which will put the translations on their cloud server, which downgrade the performance greatly.

Hello,
Indeed, we do create new posts for the translations that are saved on the WordPress database tables and then linked together with WPML Language Tables.
You translate all your content with WPML and then deactivate WPML, then you will still have all your content, only that now it has no language information anymore and will all be assigned to the site's default language by WordPress.
Let me know if you do have further questions about this.
