Having trouble uploading multiple files to a post

Hi, I’m trying to upload multiple files (30/100 images) to a post using the insert media button, if I select multiple files and press insert the editor don’t do anything and stays blank.

the question I have is, worpdress makes an ajax request to the method “wp_ajax_send_attachment_to_editor” for each image you’re adding?

I’m looking the source code and each request makes a save to the post, that’s means a hell of a lot of mysql transactions.
