Plex is adding one to two songs per minute to my library. Is this typical?

I’m wondering if the op is using the new sonic analysis with the “when media is added” option?
Its extremely slow (for obvious reasons) on an existing music library, so I imagine it will be slower still on a newly created library.

EDIT.
Sonic Analysis - has processed 6 albums in 40 minutes - Plex Media Server / Desktops & Laptops - Plex Forum
