 It becomes clear that the only way to go is IndexedDB. You start developing your app and everything goes fine.
 But as soon as your app gets bigger, more complex or just handles more data, you might notice something. **IndexedDB is slow**. Not slow like a database on a cheap server, **even slower**! Inserting a few hundred documents can take up several seconds. Time which can be critical for a fast page load. Even sending data over the internet to the backend can be faster then storing it inside of an IndexedDB database.
